I asked about the KYC, we are both not KYC. He participated once in a tournament at start, but didn't won big (like $25).
I would say if we both did KYC, this would take away the false claim. I even offered them to invite us both in discord chat or something, to show we are 2 totally different persons.
Weird thing is that the option to KYC is turned of for me it seems:

I don't know how or why they think I reffed myself, since this is 100% not the case. It seems to me this one is pretty easy to proof its not the case. Beside this, they can not have evidence of it or anything, since its simply not true.
