Perhaps they are just good at chess? Just a thought.
Hackers

In chess.com I found out many people have continuous wins like 20+ games in a row r they hackers
Or perhaps they play all of their games against Computer1-EASY.

A hacker, in the classic sense of the term, is someone with a strong interest in how things work, who likes to tinker and create and modify things for the enjoyment of doing so. For some, it is a compulsion, while for others it is a means to an end that may lead them to greater understanding of something else entirely. The RFC 1392: Internet Users' Glossary defines "hacker" as:
A person who delights in having an intimate understanding of the
internal workings of a system, computers and computer networks in
particular. The term is often misused in a pejorative context,
where "cracker" would be the correct term. See also: cracker.
The Jargon Wiki's first definition for hacker says:
A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary.
A security cracker, meanwhile, is someone whose purpose is to circumvent or break security measures. Some security crackers end up using their powers for good, providing penetration testing services or otherwise making efforts on the side of the angels. Many others use their powers for evil, however, as we are all too painfully aware. Both RFC 1392 and the Jargon Wiki provide definitions of "cracker" that support this use of the term.

Or perhaps they play all of their games against Computer1-EASY.
Or perhaps they timed out in a lot of games, leaving them in a position where they had to beat up on a LOT of even bigger patzers than themselves to get back up to their true rating.

I have a rare linux distro, the only one that can hack me is my internet provider, my internet connection to be clear cut.
