Only janitors can really safely do it though. In the case that the upload page doesn't automatically detect and ban a post, then the janitor is responsible and has the privilege of doing it. Other users don't, and it would immediately look suspicious if this thread started to get much more frequent bumps.
The problem stems more from if no one lets anyone else know to immediately ban a post ASAP by posting in this thread. IIRC @Rignak has done it a few times, but luckily I was there to notice. It's a problem with other booru imageboards also (yande.re specifically) but as they don't keep their banned artist list up to date as we do, the policy is rarely enforced. See here.
I know this statement pretty well.
The point I want to bring up is safety. And that is only something a mod is able to answer really, because there were bans in the past.
But maybe it's better to transfer this into another topic if at all...
