I'm kinda waiting for the guy, who will come and say: "Stupid thread! Don't turn this forum in another Opeth forum, jerks!" or something like this. I've heard this phrase many times on this forum. So I asked myself what is so bad about Opeth forum? I've read some threads on it and I don't know the answer. Maybe you know? So why is Opeth forum have that stained reputation?

It can't be explained, only experienced.
