Each poker site has a unique security level., it follows that there are stronger and weaker. All you can do is avoid these rooms. I used to see a list of poker room protection levels, unfortunately, I do not know where.
I am 100% sure that there are players who do play fair and cheat. This is not fair, I once turned on the screen recording and wanted to write a complaint about them, but as evil I was thrown to another table. Then I started laughing as never before, I don’t know because of anger or not
