Barring his passport getting revoked or whatever, I wouldn't be surprised if his face/ID/profile gets him blacklisted from basically every single country worth visiting. I am certain that many countries with a serious border security apparatus have the capability of doing that already and we're living in the times of facial recognition being used more and more.
Depending on how dystopic the world gets him and people like him will even probably end up getting barred from entering places like Walmart or public transport and just instantly get flagged in mildly popular areas and ejected by security.
He's probably been able to enter so many places on account of having a US passport, but that still doesn't guarantee entry and having fuckers like this do this shit time and time again will only accelerate countries exercising their right to maintain a list of "faggot livestreamers" that they reject and send back as soon as they land.
If he keeps it up he may even find himself banned from most airlines also (although I don't know if he fucks around on flights, they do not fuck around when it comes to banning people for life and I do not think it would be unprecedented for them to ban people for their behavior in general)
