Hey there.
If they have proof then they should show it. Just saying they have it is the same as him saying he doesn't have multiple accounts. And a fact is, they let him deposit. If there were multiple accounts he should even be able to register.
I don't know what would happen. As long as they have accusations, there should be a proof. Maybe sending it would DOX the player? I don't really know.
Thanks for this reference. The topics are interesting and it seems that the mods on Stake want to save face or just doesn't know what is happening with the community. Receiving unsolicited emails and mentioned on the topic there coming from Rollbit, makes it questionable. How'd they get the data of the big players and sending emails for bonuses etc.
Let's see what they would say about this.
