lichess vs chesscom players I have been playing on chess.com and lichess for more than 2 years. My rating in blitz on lichess is around 2100, and on chesscom is around 1800. Yet I highly believe that the players on chesscom are much more accurate. Like sometimes I look at the position and they don't do any blunders, 1 mistake, and a few inaccuracies in a position that's really tough to play. Like I would beat them with good moves (not the best moves) and then I would be surprised at the end that overall they played better almost every time! This is very strange. I don't know if there's more cheating on chesscom or what? I would really appreciate it if you can give me your feedback on this topic because it has been driving me crazy. Like I find it easier to beat a 1900 player on lichess than a 1800 on chesscom which is insane!

Why is that insane? According to one site, an 1800 blitz rating on chess.com is about equivalent to a 1915 rating on lichess (based on people who answered their survey and have ratings on both sites.) So, your experience of the 1900 lichess player being easier to beat than the 1800 chess.com player conforms to reality.
I think the issue here is simply that an 1800 rating on one site does not correspond to an 1800 rating on another site. Even if they used the same rating rules (which they don't), the ratings would likely diverge due to differences in the player pools.
In the end, rating is just a number, and that number means different things in different places. Just because 1800 rated players are a particular strength on one site does not mean 1800 rated players will be about that strength on another site.
