Recomendation for comments - no captcha


A few years back, most bloggers have to deal with unwanted spam comments, especially if they had not enabled comments moderation. Because of such widespread spam comments, most bloggers enabled captcha (word verification) for comments in which case commentators would first have to complete the word like the one you see in the screen shot below:

captcha for comments

If you allow comments for your posts and moderate your comments, I would highly recommend you do not enable captcha (word verification) for the following reasons:

Ever since all blogging platforms including Blogger add the "nofollow" attribute to hyperlinks in comments, the incentive for spammers to post spam comments have been greatly reduced and I have found that spam comments have reduced to almost zero.

Having to complete word verification is a great inconvenience, especially for the visually impaired who have to click on the universal handicap icon in order for the alphabets in the captcha to be read out in audio form. I have tested clicking on that icon and the resulting machine voice is practically indecipherable. I have captured it on a video. Play the video below and see if you can make out what the voice is trying to say:



In my opinion, captcha is a torture. Why subject your readers to torture when the original reasons for enabling captcha, spam comments, is no longer a problem.

Update: Looks like a few bloggers have a different experience from mine in that they get lots of spam comments. I will like to hear about your experience. Please leave a comment.

  1. I hate word verification and have only enabled it once and that was because someone thought that my not having it was preventing them from leaving comments, which was not the problem.

    But just last week I was hit by a spammer and it has been terrible on my e-mail to have to constantly erase the junk mail, even though 95% of it goes to the junk mail file. So I have been constantly marking them all as phising scams and that has lowered me down from hundreds of junk spam e-mails to about 30 a day. Before the spammer hit, I would get maybe, at the most, about 10 junk e-mails a day. I am not sure why they do not let us put a block on these junk e-mails which would really help to end them permanently.

    So if someone leaves a comment for you in a strange language with different signs such as: @#$%^*, make sure to just go to your comment editing and delete it as fast as you can. Plus they went back to some previous posts and left them. I think that anyone who clicks on their name will get the spam.

    And now because of this I have become very leery to go and click on anyone's names who I do not recognize from other sites or I have not originally visited their website.

    I just wanted to thank you again for the info. Sorry I'm not leaving more comments, but the shoulder pain is limiting me to leaving only one or two comments a day. Oh, I will be so glad when I have healed. I am so glad I found your site on someone's RSS feed.

    Oh, and how can anyone understand what the word verification thingy said. So I do hope more people read this and take it off. Thank you so much for sharing the video, now sometime I will have to try it and then maybe go visit those invisible blogspot people and let them know.

    God bless.

  2. My experience is that spam comments have not been reduced to near zero so I use comment moderation and no captcha.

  4. I enabled it after I got some foreign "porn" comments on numerous blog posts that would NOT and could NOT be deleted and Blogger help said they were working on a fix. I finally just left a few of them out of frustration and gave up. I like to be able to publish or reject a comment. Some of the social sites use it all the time.

  5. Would you want to try this delete comment utility?

    "I like to be able to publish or reject a comment."

    Do you know that you can set comments to allow you to publish or reject comments? Go to SETTINGS > COMMENTS.

  6. I just had to chuckle when I read how you think this isn't a problem anymore......these type of spam comments have never occurred on my blog until now. In the past week or so, it's happened to me three times, two different sources. In fact, that's how I found this blog posting of yours ..... googling, looking for info on what I could do to prevent this. This problem is nowhere near gone. Each of the spam comments on my blog, btw, originated in India (feedjit stats, somewhat helpful). I use word verification on my blog (don't know why people hate it, it never has bothered me when leaving comments and if it dissuades someone from leaving a comment on my blog, then, as I see it, they really didn't care about commenting anyway) and so I can only imagine that some poor student is sitting by a computer somewhere in India, posting comments and entering word verifications, getting paid pennies per post. Or something like that. For now I will just keep deleting these spam comments -- I prefer word verification to comment moderation -- but I find it annoying, so annoying.

  7. I disabled word verification on my blogs because they delay visitors to comment on my blog. But Comment moderation is necessary in this case.

  8. Hi again Peter, personally I wasnt getting much spam comments until recently and so comment moderation was working just fine for me, but just recently I had to turn on the captcha to discourage spam comments which originated from a single IP at a time and targetted multiple articles on my blog in a span of few minutes.

    I guessed he was using some kind of automated bot to post comments but after turning on the captcha I haven't heard from him since. I do think that maybe it also discourages other visitors on commenting on your blog

  9. Thanks for the post. You are very convincing! After reading this post I decided to disable Captcha on my Blogger account. I hate word verification too, so it makes sense that other people hate it too. I especially dislike the ones that are really hard to read - almost impossible to read in fact. I love your blog by the way. I wrote a review on your blog at my Trying To Make Money Online blog. I have bookmarked your blog as well, and look forward to spending more time reading your posts.

  10. I took word verification off my blog because so many people dislike it. No problems yet.

    I just discovered your blog and am finding it very helpful for a newbie like myself.

  11. I don't like word verification either but when I disable it I get spam. I am visually impaired and often struggle to read those distorted, squashed up letters, but I do have enough sight to be able to get it right enough of the time. The audio option is, as you say, worse than useless. But there is no need for it to be. I think the way forward would be to campaign for Blogger to improve their audio so that it's actually usable.

  12. Hi Becky,

    Hope your sight improves. I will try to see if we can get somebody to look into that

  13. I have had captcha validation activated, from the first day; and even that, I have received around one spam comment per month.

    ReplyDelete
  14. 1 spam per month? That is tolerable isn't it. However, I don't get spam comments for months even though I don't enable captcha. Perhaps I am just lucky.

  15. I have kept Captcha on and I have had no problems with it. Moderation is off. I'm having less traffic and so I love comments. The comments have been good so far.

  16. I'm having an issue with readers not be able to post a comment due to word verification not showing the box for them to enter the word verification. I shut down the word verification for now until I can figure out what the problem is. I did a scree print. Can someone help?

    ReplyDelete
  17. Hmm, I never thought about what to do about spam, because I'm still waiting for visitors to my blog :o)

    But I've turned moderating on, captcha off - I can't stand those images, and I'm sure it puts a lot of people off. I'd rather make my readers as happy as I can.

  18. Hi Peter,

    This is the first time I'm commenting and let me say you've got a wonderful blog.

    I initially disabled captcha but while still maintaining comment moderation. Initially, the spam comments can easily be rejected at the moderation stage but recently the frequency of spam has increased, so much so that it became tedious to delete them one by one.

    Last month I decided to enable captcha, although personally I know it is inconvenient for my readers. So far, only one spam has managed to slip through.

    I sure hope there's a more convenient way to handle spam comments.

    Thanks for your tips.

  19. God bless you, i just removed CAPTCHA from my blog

    ReplyDelete
  20. Well, I have both, comment moderation & captcha and I still get those spam comments on almost every post. To say it's annoying would be putting it nicely, and I haven't figured out a way to get rid of them...

  21. I might visit upwards of 50 blogs a day and if I had to go through word verification on each comment section, I would just not bother to comment. I am severely arthritic and it hurts to add the extra steps to all those blogs. I like to leave comments, but sometimes just give up. Why can't we just accept certain people and always allow them to comment without moderation, such as on email servers, and maybe just have to approve comments on new people who leave comments? I guess there is no easy solution. If you have been hit with spam, you will do anything to keep it from coming back, but on this side of the coin, it is not much fun.

  22. with http://keypic.com no more captcha problems

    ReplyDelete
  23. Captcha sucks. I use GASP for Wordpress, a simple check box and I'm 97% spam-free. I still use moderation for first-time commenters.

    ReplyDelete
  24. P.S. You have CAPTCHA & moderation. BOO!

    ReplyDelete
  25. sigh, yes, getting too many spam comments. Maybe I will turn it back off again later, or perhaps not.
