The same person is making the same kind of disposable sockpuppet accounts to troll bump the same posts again and again. Their comments get deleted, but all that really does is mask just how many of these accounts have been made. Whenever one gets flagged, they're often accompanied by a deletion of two or three others that were created at the same time, just waiting out the probationary period after a new account to get their chance to spam as well. This person has kept this up for roughly a year, now.
A similar problem exists with another user (unless by some coincidence, they happen to be the same person who just has nothing better to do with their life but make disposable sockpuppets for banning), seen here.
While this is a minor nuisance at most, which takes more effort on the part of the troll than the people needing to constantly ban their sockpuppets, it does strike me as still too inefficient. Can't something be set up to prune some user accounts clearly being set up several in a row from the same user with basically the same name as the last one that was banned but oh so creatively made distinct by adding one more "z" thrown onto the end? Or for that matter, just make a script to ban someone who bumps the same 11-year-old posts as their very first comment? Or, you know, just lock the comments on those images?
