Valids points mate, but I think all these guys are trying to do is educate people a bit.
Hardcore is a relatively small scene dependent on a youth audience who tend to be fairly prolific filesharers.

I don't think they are trying to take down all p2p networks or kill servies, just asking people to support the scene by paying for music rather than stealing it and sharing it illegally.

Which isn't an unreasonable request IMO.
