First win against 1900 in blitz (unrated). Accused of cheating in the chat :(

He got banned after he didn't review his membership lol.

Since RD moves ratings quickly, it doesn't matter what rating a player starts at.

Also, the best players on lichess are 3000 while the best on chess.com are 3200, so 2700 lichess is > 2700 chess.com even though at lower ratings it's opposite i.e. 1700 chess.com > 1700 lichess.

Your friends are cheaters.

What does an OTB rating have to do with it? GMs have been banned (and admitted to cheating) on chess.com.

This account of mine got banned for fair play violations because of reasons unknown. I never cheated on my life, yet I apologized for it as the fair play team didn’t accept they were wrong. It doesn’t make sense…

blatant cheaters aren’t banned immediately but I got banned cuz of “fair play”

meh -- sore loser.  Clicking it rapidly to emulate blitz, I see nothing white did that was remotely questionable.  Black got caught uncastled, with predictable results.   I would have expected the 1000 to drop a piece just cause 1000, but the game was very short and 80% focused on one square, so its not too hard to believe that there wasn't a lot of room to screw it up. 

What was the account name?

This account 

That doesn't make sense #54

Banned means....forever. If your account is active...it hasn't been banned.

No, they let cheaters come back all the time.

I'm guessing @ajayjha25 didn't know the rules (like playing two accounts against each other) or thought the cheating was too insignificant to matter (like cheating in unrated games).

I once had a winning position against an IM from Argentina playing in a simul.  However, I managed to muck it up and ended up losing.  Afterwards he analyzed the game with me and was quite complimentary.  I told him I had a 1540 provisional USCF rating as I had only played in one tournament, and he was quite surprised.  Unfortunately, work pulled me away from chess for many years, and I am only now returning to it, and am quite rusty besides.  The point is, if I hadn't bungled the ending of that game I could have beaten an IM, so it IS possible for a lower rated player to beat someone much higher, but not very likely.  If you played clean and fair, then congrats.  If you didn't...well, does a cheater feel shame?

If you got accused of cheating by your opponent, you should be happy because he thinks you are playing well

From the game as far as I can see the Highbie overlooked one move and his position collapsed - we have all been there. 

Regards cheating, chessdotcoms own stats indicate titled players are at least ten times more likely to be cheating compared to multitude of lowbies. As a low-level player myself cheating is subjectively extremely rare.  At low levels, sandbagging accounts are far nastier, something chessdotcoms cheat detection system appears to be totally useless in dealing with - there would be technical reasons for this as any titled player could create 100s of sandbagging accounts without immediate detection (as could anyone else!). Sure, the sandbagging accounts eventually get banned but this overlooks the damage done.  As a lowbie this is the one of the reasons I no longer play on this site - the other being that I have bought about half a dozen old dedicated chess computers which provide far better, more consistent and more worthwhile games for my tastes - with zero hassles.

Considering the ability of bots to play suboptimal moves that win, I don't take it as a compliment. 

Good game. Your opponent completely blundered the knight which was pinned. It's quite natural to get accused when you beat higher rated player. Doesn't look cheating to me in any sense. It's natural to get high accuracy score when your opponent blunders within 15-20 moves. So, chill and keep playing good chess. Have fun

The only thing more pathetic than cheating in an unrated game is accusing someone of cheating who just beat you in an unrated game.
