Yeah, I don't play here much anymore, cause they are pushing the memberships so hard. I am mostly on lichess now.
Yeah well, everyone is pitted against players of similar rating unless you change something in the options, but I didn't really try that. So, no matter how good you are, there is always a bigger fish out there.
Except if you are a super GM, that is.
As for the membership, if you become a CM, and you can prove your identity, you'll get diamond membership for life free of charge, if I am not mistaken. You should google search for details.
Look at the graph. How is the majority 2000+??
