@Jan-Meyer This is online chess and not a FIDE sanctioned event. Its not an actual problem no, just a very rare incident that would require a significant amount of work and resources to prevent for no tangible benefit. Problems are things that would disrupt the games and bother the players. If we absolutely had to follow all of FIDE rules, we would need arbiters.
OP is just a bit upset that he lost. If it were really about the implementation of FIDE rules the biggest and most important feature would be to call an arbiter to the board. He should have the power to make rulings including penalties for "unreasonable draw offers" that seek to distract or offend a player.
