That said, I have played under ten corr. games in my life (all on this server, all in 2014). I have stopped after my three (!!!) last opponents, all rated in the 2000s, turned out to be cheaters.
How did you detect them to be cheaters while the game was in progress? The only reliable way I know is to match their moves to a computer, and it seems like that method would be forbidden during a CC game.
Strong players have developed a good feel for what human play is, compared to engine play.
So they can smell a rat.
Correspondence Chess through snail mail or on a server is fine if you don't have time to play OTB due to family obligations and other reasons it works out really well when both players respect the honor code and don't use computers or consult third party players.
True CC players don't have to be strong armed when they give their word to their opponents and the organization they play for they won't use them they really mean it.
So you're back...
