"Desirable" and "mandatory" are different concepts. If a decision was made based on this, then it generally doesn't comply with the rules of this tournament.
When a football player ignores the referee's request, he leaves the field with a red card. This is the case in all sports. We are no exception.
By the way, since we're having some sort of "discussion," I also have a question. How long should we wait for a response from an opponent to an email? I'm not even the host in my game, but honestly, just sitting around doing nothing is boring. I haven't received any proposals from my opponent yet. Considering that I didn't play in the 1/32 round... in general, it's a pity to waste weeks like this:(
Не стремясь приобщиться к основам пришёл.
В прошлый раз утащил я молитвенный коврик,
Он истерся до дыр, - я за новым пришёл.
