Yes. If you played enough as a human then you can't play a completely anonymous/pseudonymous game. Just like if you have written 10 bestsellers you probably can't write even a short pseudonymous newspaper column without someone recognizing your style. They can't be sure from that little information, so you aren't completely exposed - but if you keep writing a series of columns they'll be more and more sure. The same thing with chess. Play chess under your real name (or write texts or draw illustrations whatever) and you'll never do so anonymously again. I'm not sure what's so upsetting or revolutionary here.
