So I guess 711ch is dead.. again.
In the few years it existed, it never really got off the ground. There were no raids, besides raids done on the site itself, in a twist of irony.
I think heyuri is probably too nice-spirited to have raid threads (and too slow), but I wish there was a cool raiding spot on the internets. Flooding Japanese menhera streams with engrish comments, and micspamming IP cams used to be so funny.
