It is okay, chess.com will not ban you, they are reasonable
HELP!

Chess.com does not ban based on reports. All a report means is that they will look at you. If you didn't cheat, chess.com will know, and nothing will happen to you.
It is unfortunate, but true, that there are disgruntled players who react like this to a loss.

Guys, I got reported by a person in rapid. I had 91.2 accuracy and he said
"Using an engine will destroy you, I will report this to chess.com." What do I do now?

First, make sure that you're following all the fair play rules. There are some that people might not realise are considered cheating: https://support.chess.com/article/648-what-do-i-need-to-know-about-fair-play-on-chess-com
If you're following all the rules, though, you don't need to worry. They're very careful to avoid accidentally banning an innocent person. Simply getting reported won't get you banned. They never ban anyone just because they got reported; they look for clear proof that the person actually is cheating.
If you're playing clean, you have nothing to worry about.
And if the other person is abusive, you can report them for that.

I’ve gotten reported in bullet by someone who was higher rated than me was (1700 at the time) and some people can’t accept that they just lost lol. I’ve remember anger reporting a 1800 I lost to in Rapid because I was tilted and angry. I looked at the game review and I had about 65% accuracy. Stuff like this happens all the time. As long as you know you didn’t cheat you should be fine.

Well... I saw a game where you had 91.1 accuracy... and it looked like you cheated:/
are you sure?

They check if you used an engine. There is a difference between human moves and engine moves, and if you didn't, you don't have to worry

this is why I very seldom play against people except over the board. I play against the bots now because they don't cheat they don't argue and I can play than anytime and also the bots are great while practicing strategy. Don't worry about this person.

sure that he cheated? no...
It just looked suspicous that when he was given a chance to possibly win, he began to look like he was using an engine...
