Over about 243 correspondence games, only about 14 or 15 of the time out wins (which is what usually happens with cheaters) were against players who's account's closed, or says that they cheat. (2 of them against the same player). There's maybe about 5 of them with inactive players, which could be cheaters but there's nothing for sure. So that's not even 10%, most of them 1-2 years ago.
What this means is, (at the very least!) over half of time OP aborts a game, their opponent was likely not a cheater. So it's probably fair to say it's just abuse.
And then there's this game, which I got 0/0/0, so I must have been engine abusing. (Eyeroll) lichess.org/E6nIKxaj#20
I don't know if white was cheating, but if they were, it didn't work.
