I think many cheaters think and tell them selves that they will learn by cheating so that they can see what to play in different openings, etc. Very anoying.
cheating on online platforms

There is a website that shows how many cheaters you have met.. I usually meet around 5 per month... also, I get accused of cheating several times per day. It kind of ruins the game when people start to accuse me in the middle of the game.. I don't want to disable chat because there are kind people as well...

I can remember one game both played nice openings and so it went until about move twenty three when my opponent suddenly quit....?? I looked at the review and lo and behold we had played perfectly from the analysis . I quickly messaged my opponent effusive in my apologies that I had not cheated until I looked closer .... I had misread the results he was on 100% to my 99...whatever . Why that cheeetah - true story. If such can occur to me without cheating then when should I call out somebody else so that rock remains to this day unthrown.
People cheat in every game not just chess
A good tip to avoid cheaters is just abort games that are under a year old UNKESS it just looks like an alt but it's an actual play (for ex with a fida rating )
The easiest way to catch cheaters is level of play(not accuracy btw unless it is like 90+% 20 games in a row) and time used ex moves every 3-10 sec
But honestly maybe 10 percent or less cheat most days it will be around 2.5% but sometimes it san get worse so try not to worry about it let chess.com handle it report and move on don't try to call them out/report on forums
But don't assume your opponents are cheating just cause they play well (and don't get paranoid it ruins the game just as much as cheating does )
After all your opponents probably weren't cheating
I'm guessing it's prob less than ten percent more like 2.5%
I was just saying you might get that if your like super unlucky

When a player plays twice his/her ELO without any mistake either the ELO system is failed to recognize the strength of the player or .....
Beside that its is not the main question, the question is why do people cheat in a game which has no positive or negative impact on them.

It affects my confidence, to say the least. What I can't comprehend is what they get out of cheating.
1- do they get better at chess? No
2- does their online ELO matter in life? No
3- does the inflated rating make them better over the board? No
I don't see the point of cheating and ruining the game.
