I'm not entirely sure how to proove it's him better but I'd be happy to screenshare with a staff member or do anything else to prove it's the real him.

Since I considered him a friend the conversation is infinitely long so again, I'd be happy to screenshare with a staff member to show the entire log.

As you can see, he hasn't responded for 5 months.

I have pretty much infinitely more evidence against this guy, probably enough to permanently ban him.
