I love playing Chess on this site, but in the last few weeks im encountering more and more cheaters, especially in Rapid Chess. In the last 50 matches I've played, there have been at least 10 people using an engine. And that's only counting people who are using an engine obviously. There are probaby more cheaters just using the engine in crucial moments. It just kills my fun completly and demotivates me. And i don't feel like there is anything that chess.com does to combat this. I'm reporting everyone of them, but rarely get ELO back. And its not like I'm a sore looser, the guys I'm talking about are mostly new accounts with a accuracy of 95+ in every game. How are they not getting banned?!
Im completly demotivated to even play online Chess anymore. Ofc i could start play mor Bullet wich is probably harder to cheat in, but thats not what i enjoy in Chess. I really hope it gets better someday, bc this situation drives me away from Chess.com
