How do you deal with a known "board killer" who stinks up the place with countless new threads of inane drivel that no-one is really interested in reading or replying to? I'm talking about an individual who is so utterly socially inept that they don't recognise that although they are not technically spamming, they are having the same effect on the readability of the forum.

I suggest a junk forum. Move the garbage threads there, then the rest of us can enjoy the board. And just maybe someone will take a hint.
