Hm, this is a tough question.
I think i just respond to individual posts, but after a while, after reading someones posts, you might realise that they are a complete idiot.
And from that point on, you treat them as such.
I don't think that's "beef" though.
And skampoe is an isolated case, he has huge mood swings and stuff like that, and sometimes holds month long grudges, and other times completely forgets about things.
Pay him no heed.
