This is a business behavior - if somebody is paying, he will get more, but i dont think, that he will get easier random opponents.... Just regarding fair play - i am not sure, if it is the same procedure for closing a random account and closing account with paid membership - as you dont want lose a "customer", maybe, they get some warning first or so - we dont know as the cheaters and Chess.com both would not make it public, if it is the case.
I believe that Chess.com has a very good interface, though the moderation is a bit poor. Many people gat banned for small things, just because people who have bad intentions do those same things for attention. There is one player named Macca who was IP banned because he was speaking about his mental health problems and thoughts, but it was proven that a hacker said these things on his account. Chess.com does have good staff, but with support, it is a bit iffy. Sometimes you'll be connected with a kind staff member who will help you right away, and sometimes you will get a staff member who is a jerk and either turns you down or doesn't do anything for you for months at a time. Not to mention that they are quite biased on their policies, typically helping people with memberships rather than those who can't afford/don't want them. Overall, though, the Chess.com community is strong. If you want to see proof of their unfair moderating system, there is a forum in the OTF forums here: https://www.chess.com/forum/view/off-topic/dear-chess-com-support-107270115
Shout out to this guy for understanding what I'm saying. You are inherently favored for paying money. Isn't chess supposed to be fair and based purely on experience?
