chess.com accounts flagged for violating fair play often get banned...but your account is still here (how else could you create this forum thread?) Are you sure you were flagged for fair play, or was it just a warning about fair play rules?
If you really were flagged for violating fair play, then you can contact chess.com support and they may "clear your good name" if they recognize that everything was done fairly.
I got flagged for Fair Play- WTF?. I am a 365 and play minute games. I wouldn't even know how to cheat. What can I do to clear my good name????
