I've recently realised that the forums has been really messy and nobody seems to be taking care of it so my suggestion is making a forum moderator to moderate the forums to ensure a clean forums for users as it'll be easier to navigate and faster to reply to posts. If picking a forum moderator is a no no, I suggest setting up the anti-bot plugin which I can link you to. I'm experienced with MYBB and this just some things that needs to be pointed out.
