I don't care if people cheat on Zwift. They are strangers, so it doesn't matter to me if their stats are real or not. What does it matter if I'm racing a weight cheater or someone genuine with the same apparent W/kg? It would be different if there was money involved, but for me the motivation is just to beat whoever I'm racing against, regardless of whether their performance is real or imaginary. I know my numbers are real, so I'm not deluding myself like cheaters are.
