this is a complete failure on the hosts behalf, and obviously on the act fisher. there has to be a certain point where the host steps in and tells the person who has notoriously fished for act wins that no, he can't request an act on a monday. Technically it might break the rules, but in a tournament like this, we should follow the spirit, not just the letter of the law.
it's also pretty strange that the Smogon community as a whole is still letting this player participate when he has shown time and time again he does not try to complete his games in good faith, and this is another glaring example.
I feel bad for MANNAT but I would do the same thing if the host is giving me a loss on a monday lmao
