Apologies if this is 'necro'ing my own thread (I've still very little experience with forums in general as a whole), but on the blacklist topic:

You only have 200 slots for the blacklist.

In just a mere week or two I have completely filled it simply on account of trying to blacklist the "club" spammers to clear out their spam entries.

THAT is how bad it is. And it doesn't help because those same spammers seem to have other accounts to just continue the damn spam.
