As described in A moderator flag on a comment silently deletes it even if the "other" option is selected, if a ♦ Moderator flags a comment as anything, the comment is immediately deleted.
I just saw a few comments on Cognitive Sciences which were obsolete: someone commented that a reference should be added, and the OP added a reference. Both have placed subsequent comments so I know these comments have been seen.
I flagged both comments as "obsolete" to auto-delete them and also leave a message in the log so my fellow mods would know what I did and why:
Is this acceptable? I ask because I also read this answer:
That said, if someone really wants to flag 500 posts and abuse their power to get a gold badge... more power to 'em, I guess, but their diamond and badge just might disappear
I really like my shiny ♦ so I'd like to keep it for a while :-)
