Sorry for the delay for this week, there was a lot to go through and I've personally been very busy.
The match result will stand as it is.
NRB (Spicy) provided us with proof that the player without reasonable doubt was him. Proofs of his E-mail being shared across his MKB / Nintendo Account / Switch were provided. On this same Nintendo account, a conversation with a representative was also shown that talks about him changing his FC. Because of this, his points will stand.
