Now I think It would be cool if you could ban people in your threads that you make.
Yes there is a report button but noone wants to use that
Obviouslyt you can't ban moderates etc
but if someone is spamming up lets
say your clan discussion you may ban them from your thread
Just a suggestion.

Not supported? Why?

Obviously it would be terrible in public boards but what about clan discussion?

Let's play a game of Jeopardy.

What is blacklist?

This would be good for market threads to.

I think this could be good for Clan and Org threads/boards. Not sure about the rest of the forums though.

Why not. If u don't want a certain fucktard to post on your thread...it could save a few pages of useless posts every now and then.
Blacklist xylon ftw

Depends on the location of use. Obviously it would have different effects in market threads, clan discussions and elsewhere as aforementioned.
