Titled players of course have their credentials checked by chess.com; as for the rest? I doubt that there is any verification. Like you I've seen numerous "dubious" rating claims. It's like all the kids who put GM in front of their name; they're just having fun.
Are FIDE Ratings on the profiles verified by Chess.com?
I've seen many players having their FIDE ratings posted in their stats/profile of chess.com
This thought came to me when I realized I had won against a few strong players (above FIDE 2000 as listed on their profile). I don't see any chance of 2000+ players losing to a casual, unrated player like me unless they willingly do so. Now the question is : Are their ratings genuine and well-verified by this site or can they write anything on their profile?
No, it is a free-form field that a member can enter any number they want in it.
