This forum is always getting randomly spammed, & sometimes even mass spammed. The anti-spam system doesn't seem to be preventing them from posting, but there's nothing I can do about that. We do - or at least I do - get rid of them as soon as we see them, but some do slip through the cracks. At least getting rid of them is easy because if I delete a user it deletes all of their created topics/posts along with them.
In regards to your post, you would need to talk to Simon about that as he's the current lead developer of the engine.
& as Esmeralda said, you would be better off joining the discord server where everyone is a lot more active, & so far, there's been no spamming going on either.
