Are you making your first move as either Black or White within the first 15-20 seconds of the game start? Other than aborts, the server also looks for other activity such as
intentionally disconnecting during games
stalling to make opponents wait unnecessarily
Any of these activities could trigger the Fair Play Warning and potentially restrict your play for 5 minutes between games.
