How about this gang?
The Scam Busters Gang
Hehe thx for the suggestion! Added! With a few modifications; I hope you don't mind.
where there is Gang there also must be a Bang. Gang-Bang.
I remember Jet Cash had a similar thought, so there is hope:
I don't seem to be in any gangs. I was going to say that if there is a gang bang, please can I join in, but I'm not sure that we have any girls here any more.
What about Gang of Trolls and Lunatics or Gang of Scammers and Cheaters?
Cheaters Gang is mentioned already and scammers are mentioned as a faction of this mother gang. The trolls and lunatics are also included, in the "etc" from the end of the mother gang's description

The Cheaters Gang - [...] This gang acts also as a mother gang, containing various bands, such as The Merit Abusers, [...] The Thieves, Scam Gang Mafia etc.
