Comment Deletion

Currently there is a Blogger comment issue. We, the mods, are not deleting your comments. If we remove one, we remove all traces of it and don't leave the removed by author or admin track behind. We're terribly sorry also for the comments that you and we have lost. No word yet on whether any will be restored when they repair this.

I checked Blogger trouble reports and found this answer:

Blogger is currently fixing bugs in the comment code of Blogger and this (mass comment deletion ) may be a residual effect.
