Yes it is possible to recover deleted comments, but only if you moderate comments via email and you don't delete those emails which had been sent to your chosen address. I will use as an example the comment which inspired this post which you can see in the screen shot below:
This is how you recover deleted comments. First locate the relevant email with the comment. If you have not set your comments to allow anonymous comments, go to Blogger Dashboard, SETTINGS > COMMENTS and set it to allow anonymous (anyone) comments, only temporarily if you wish. Now go to the post where the deleted comment you want restored is. You can do this easily as the email for comment moderation has a link to the post (plus a link to the commentator profile which you would need later). Right click and chose open link in new tab (preferable) or open link in new window (if you don't use a browser with tabbed browsing like Firefox.
In that post, click Comment to open the comment editor, go to the email, copy the comment and paste it into the comment editor. Now your comment editor should look like the screen shot below if you had set comments to allow anonymous comments (Anyone). Tick Name/URL (see screen shot below):

Go back to the email, right click on the commentator name (highlighted with red ellipse in the screen shot above), select Copy link location to copy the URL of the profile of the commentator into clipboard. Go to the comment editor and paste the URL into the box for URL (see screen shot above).
Go back once more to the email, copy the display name of the commentator into the box for Name. Now all you have to do is to publish the comment and the recovered comment will not only have the comment itself, but also the commentator's display name which is an active clickable link to the commentator profile. The only difference from the original comment will be that the photo of the commentator will not be displayed.
Note: If the original comment is Anonymous which is not clickable, then you can only put Anonymous in Name or tick Anonymous instead of Name/URL

ReplyDeleteThanks a lot for this blog. That's really helpful.
ReplyDeleteIf it is just missing tool icons, try using a different browser. If you are residing in Singapore and Singtel is your ISP, refer to unusable distorted post editor
ReplyDeleteHi Peter
ReplyDeleteThanks a lot for the useful info.
I want to add background colour to the sidebar title / header. pls show me the way. I also want to increase the footer size and divide it into 3/4 columns horizontally. Is it possible?
pls help me...
For the first part, please refer to Change sidebar title background color.
ReplyDeleteRegarding the second part, it will involve quite substantial tinkering with the template. Ask me again later.
thank you thank you thank you thank you!
ReplyDeleteI was so excited this morning that I actually got x amount of comments (I won't bore you with my pitiful status :)) that I deleted all of them.
Yes, the words irony and idiocy sped along nicely through my mind, but thanks to you, that's all solved. Not as easy as just clicking on PUBLISH, but still.
Thanks. Again.
oh, thank you!
ReplyDeletethis was most helpful!!

You can if you have opted to receive email notifications for comment moderation or just comments notifications and have not deleted those emails.
ReplyDeleteSorry reread your comment again. If you have opted to receive email notifications and have not deleted them the method for restoring them all is the same as restoring 1, just do them for each one by one. The instructions for restoring 1 comment have already been given in this post.
ReplyDeleteGrazie Peter@Envroman, un post davvero utile!
ReplyDeleteAnche a me è capitato di cancella un post inavvertitamente...grazie a te l'ho recuperato!
Speriamo però che Blogger trovi il modo di spostare i commenti cancellati in un cestino così da poterli recuperare...a presto!
