Yes, it would show up as Deleted User and then some letters/numbers. Example:

However DSP has been regularly clearing out his moderator discord chats in order to prevent leaks from coming out after the last round of leaks. Outwardly he likes to say there's nothing in there that can get him in trouble and that he's not nervous about leaks happening, then quickly back peddled to say "it would all be fake anyways." I asked, but there is no Deleted User chat history in the Discord.
I believe I included in the WWE Champions thread I was waiting for confirmation on the 16 digit unique ID before I posted about the account being the same in the WWE Champions guild Discords and the secret moderator Discord.
I can say I have had multiple DSP moderators at this point tell me the 16 digit unique ID code for TheyCallMeDSP#4058 was 429043479683923979 taken from the moderator Discord and matches the unique ID code for the same account in the WWE Champions guilds.
For those of you who don't use Discord because you're straight, you
can change your account name at any point. You can only change the identifying four numbers after the # by paying for Nitro, and TheyCallMeDSP#4058 never had the Nitro badge to be able to do this (It costs $50/year for Nitro). But you cannot change your name AND four digits to the same name+4 digit combo as someone else. You get an error message for that. I believe I posted this in the WWE thread but I think it bears repeating here.
If you're continuing to doubt I will point out another curious detail in the "impersonator" DSP Discord account that has since been deleted:

It was created right after he was banned during Far Cry. Unless someone made an account to sit on for YEARS to try to age it up to be credible only to delete it after it was exposed instead of keeping it around as "evidence" to "try to get him in trouble" (his words from Yakuza tonight) then they weren't an impersonator and was more likely to be a the real deal.
I think this counts as confirmation.
