If he is dealing with CP
Report him to
http://asacp.com/
He will be taken down
If he steals your content
Report him to his host or sue him
He will be taken down
If you dont like him, Ignore him.
This is the only way to deal with these things.
But the continuing shouting about CP
is utterly useless if you, that has found it,
did not report it to ASACP
