I'm probably misunderstanding (not a law guy) but that seems like a strange mechanism - members of that group transfer legit patents to the patent troll, on the condition that the troll doesn't sue them. This seems to be arming the troll with the tools to attack outside groups - making it somebody else's problem is not the same as eliminating the problem.

I'd rather see the Cloudflare approach, beat the barbarians back from the gates then destroy the troll's IP inventory with examples of prior art.
