The Scam Busters Gang
Supreme Leader: ICOEthics (although not active)

Reputation: allegedly, exposing scammers in the wild.
Activity: Scam Accusations board, of course. Doing investigative work in the background, very quiet group. But as soon as they have evidences and proofs of scams (ICO projects with plagiarized whitepapers, fake teams, fake give-aways), they are going to exposed it. Those accused can defend themselves, but 90% didn't have the balls because they are caught with their pants down.
ANN: none.
First mention: I can't remember
Misc: Everyone has its own ways of finding those cyber criminals, the leader has show some of his tactics and so as the rest of the gang. That's why the gang is slowly growing in numbers every year. Myself didn't involved that much, just late 2019. So there could be others there who may want to join the gang in the coming years.
