Joe Francis -- Steve Wynn Is Screwing Over Girls Gone Wild [VIDEO]

Joe Francis is on the attack ... claiming Las Vegas mogul Steve Wynn is poaching Joe's GIGANTIC porn company, Girls Gone Wild, just so he can dismantle it ... and it's all out of revenge.

TMZ broke the story ... GGW is in bankruptcy and the trustee engineered the sale to satisfy Joe's debts.

Someone came along and anonymously tried swooping GGW up, and Joe says it's his archenemy, Steve Wynn.

Joe believes Wynn continues to harbor a grudge -- Wynn sued Joe and got a $20 mil verdict, and a jury concluded Joe defamed Wynn by telling people the mogul hired hit men to kill him.

Joe believes Wynn is behind the purchase of GGW and his intent is to buy it, fire all the employees and then dismantle it.
