Imageboards are internet public shitting streets. The whole point of them is that everything is transitive and everyone is anonymous. You can't sanitize it to keep the "bad actors" out or else it defeats the point and it becomes a rulecucked hellhole like 4cuck where jannies remove everything that makes their clitties leak.
If anything, if you really, really want a rulecucked bad-actor free website then you already have this one. Hybridizing the sharty defeats the point of it being an imageboard, hence why I said it was a terrible idea.
