Couldn't any strong player be considered a cheater a priori until they prove otherwise?

Most leading players have an ironclad alibi that cannot be changed – they play live, in clubs, with witnesses who are also their rivals. I can say about Stinger that in the game, he is an avalanche sweeping everything in its path. About Antal – a large predator on the hunt, about Cobra – vast experience, about Andre – extreme focus, about Joker – some adventurousness and maximum risk, about Bishop – the psychology of a winner.
I have seen these top players in action; it is an impressive sight, and you could charge money to watch it. I also saw Vitalik in Michurinsk and Krasnodar, and I can't say anything bad about him; he is a strong player, but there have been and will be many like him. I didn't see when he became a brilliant master.
I only read that he played in the final of the $1000 Portal Tournament against Markon and lost 1-2.

So, this is what I have about his club play.
1. CIS Championship in Krasnodar – a quick exit. However, I also had a quick exit, and so did many others. The top 8-9 players were too far ahead in terms of skill, and the rest were left behind.
2. Michurinsk Tournament. 2 wins and 2 losses. He lost to a good player, Mizrael, and to an average player, Khvost.
3. Chaos League. He took 3rd place in one tournament. A very decent result, but many good players made it to the top three. They couldn't win the tournament; only the top players won. The question of Vitalik winning a Chaos League tournament never arose.
4. Mini-match with Markon, a strong player but not Stinger. 1-2.

These results don't match up with his online tournament results. This is where the doubts come from. Other old players have the same doubts; Bay, for example, remembers both the Chaos League and Krasnodar. Add to this the stories about save files...
It's not even about the final result, but about the subtleties of the game that immediately distinguish a master of Antal's level from just a good player; a good spectator can immediately see who plays how in a live game.

If there are club tournaments, even if only occasionally, the level of distrust will immediately decrease because it will immediately become clear who plays how in reality.
