Please don't look for posts from /u/hardtimes without a severe CW for scat and who knows what else at this point.
I think it's worth considering what kind of damage trolls, wreckers, and edgelords in general can do with such images in the future. @Frank@hexbear.net may have been right in that struggle session today; such open image posting may be a mistake.
You have a good point with the posts already being vulnerable to this, the only difference though is comments are 1) much more numerous and 2) much more likely for a mod to not notice. The nature of the problem is the same as we had before, but the commenting issue is just a much more severe and difficult to deal with version of it.
Furthermore you get a notification if someone comments on your post or replies.
