Dropping a few facts there just as one does think that's the time to steer clear of the mysteries and false assumptions
Lexa and Mike were blatant cheaters. Their whole career, starting from Interplay times is built on deliberate software abuse. Key people in IMT almost never suspected them of anything which is at least strange.
Troy ( Trojan ) from Indestructible, later Immortals - mostly known as bot/modding enthusiast - is one of the people behind coding advanced cheats ( which are, practically, all of them beyond regular CE ). Immortals leadership, although, never had a conclusive evidence. Some of them had more presumptions some had less but no real trial had ever been taken.
Haron, Brian o Conner and Kartels are whatsoever the identities of the same person, to the extent we could even put kartels identity to someone as it had been a shared one for years.
With Tankist mostly taking shots of that caliber, Oolong aka max-anthrax is a real pedophile in real life with a proven attempt of dating a minor. Many oldies in Russia know that not sure why hadn't it even been made public.
Voodarius aka Darkminator, Fifth Element and thousands of other smurfs ( apparently, the first owner of the gamezone24 account I'm using right now ) had never been a russian kid. It is indeed a person who's past his mid 30's right now like some of us are with an immigrant background. He's observed around since AT LEAST early 2004.
Campers cheat pack is a pretty pejorative mean for a grouping of wares barely connected to each other and developed by different people in the early 2000's. Some of them were proactively used by the infamous Dutch brothers, however not all of the originators share Campers ancestry in their tag history.
There's also a bit of stuff about old GameMeccans, however I don't feel like digging that deep right now.
