"I am losing he is a cheater"- Mentality???

Hello lichess community
As you see I am an International Master. Again, I was accused of cheating and slowly that is getting on my nerves. What is it with the whole mentality that everyone around you is a cheater???
First of all, my latest case. Since I have nothing to hide, this is my side of the story. My name is Jaroslaw Krassowizkij, 2440 Elo, Germany; I played 2 years in 1st German Bundesliga, and I am playing my 3rd year in the 1st austrian League. OTB I have beaten already GMs ~2600, drew Shirov, enjoyed a fight with Ivanchuk and Vachier Lagrave. I had to sign some anti-cheating contracts and I am very positively sure I am not cheating by using my head.

So here is the match against one decently strong opponent (2330). I think I do not do him any wrongs, since he is sure I am cheating so he can stand with his name for it. So the issue is, I am not playing 'too seriously', in detail all I do is not to use any of my deep preparations I use for the top players, just because it tends to be boring just repeating moves over and over again. Instead I just try new ideas, other openings etc. From then on, I just enjoy crazy chess without any fear of losing, but just for enjoyment. For that case I played also 1.e4 though I barely play it OTB.
So here is a brief summary of the games if you don't need to watch them
G1: Crazy Stuff, I just sac a pawn for some Initiative, he fails to defend, I am not precise he gets counterplay but loses on time
G2: Exchange French, I get to outplay him on even ground, miscalculate completely, he wins
G3: I get a better endgame, blunder a pawn, still have an easy draw, play for the win and grant him a win this way
G4: Again I get progressivly a better endgame by putting pressure, fail to calculate the right pawnendgame and happen to lose a 3rd time a better position. These were his only 3 points.
G5&7&9: I switch my strategy as white- I let him have his pet opening I played as black once. Maybe mean, but as a psychological experiment- Once he gets that I know his opening, will he stick to it, trying to improve it (though unfortunately it is objectivly bad for a reason after all), or will he switch it, does he even have a "real" opening after all? Btw, my whole strategy is just, hold on to the pawn and win the endgame. That easy it actually is.
G6&8: well, he slips on even ground and I win it.
In fact, he did not even win a single game on is own, and I was pretty upset by losing games when I had all the advantage. But in any case, he could have left any time, asked me why he fails and I would have answered, anything. But instead he accuses me of cheating. This is not the first time for me, but it gets slightly annoying. And also, Shouldn't there be also measures for wrong accusations or somehting? I mean he will never apologize if he is wrong, he just sends the report, does trouble, for me, for the stuff and he has no disadvantages. And on top, he has 0 reason, other than his bullshit claim that he had 0 chances against me. And I bet he did not spent 15 years:2h/day for chess like I did so he should be the one taking some credit for these accusations. I am used to it now, but the first time it did hit me pretty hard. And I bet it will also hit every other non cheater, if you do not show respect to his good moves. What do you think? At least one sign like "this player is unsportsmanlike" would be a good idea I think, so the players in general would try to behave something more on this site, don't you think?

Just ignore it and block him. Problem solved. Its not worth getting upset over. Some people can't handle a game and act immature. Ignore them.

Exactly, the block option is very usefull.
It needs just a click.

You're right. but the problem of cheaters is huge. Once he was playing in the coffee bar face to face. Just yesterday I denounced a cheater and within an hour the site banned him. ... is already the third in two weeks!
I am no longer young, my score was about 2000. It's all my life I play and I know a program ....
you live serenely :)

Happens all the time, internet yo-yo's make unfounded accusations. Personally, it is forgotten about and ignored moments later. What the point is of a long post, the creation of a thread making an extensive denial that no cheating occurred is a head scratcher.

I was accused of cheating just one time.

The guy send me a message saying that I'm a cheater, that I will be reported and a lot of f words insults.I did not take it personally because I know some people are very upset about losing.

Actually that message make me very proud. That means I played so well that my opponent could not even imagine that I was not a machine. He thought winning me was impossible. That I was unbeatable.

What I want to say is that you can take these things for the good side or the bad side.The decision is up to you, but I prefer the first one.

Good point. People will say they were "insulted" by words. They are only insulted if they allow themselves to be. When knowing the remarks are unfounded they can be ignored. There is no need for explanations to the general public as most can see through that stuff.
Now, if slander or such can be proved and damages are incurred,of course that is a different situation. However, everybody knows accusations of cheating at internet chess are so common they are laughable.

In Rakanishu's case, I believe you might be able to report your opponent for "Insult". However if they just call you a cheater, I don't think "Insult" works, and all you are able to do is just wait until the mods read the report and realize that you are not a cheater. I think maybe it would be nice for someone to get shadowbanned (can't talk in chat) if they continually call people cheaters publicly though. I don't see the problem with reporting someone, but if you report someone, you shouldn't tell them that they are a cheater.

Think about it this way: Your in-game decisions are so good that you get compared to Stockfish. [Never happens to me, because I'm bad at chess.] Good for you!

To, two or too ?

It's hard :)
