One time I saw a blog post claiming that Brendon's personal instagram account is run by an intern and not him and........ No, that isn't remotely true for various reasons:
He posts various photos of places he's personally been to, such as Italy. Why would he drag an intern with him on a trip just to take photos of Italy for him? Makes no sense.
He has said to acknowledge selfships in various interviews. He has shared selfship stuff on his IG stories many times. He wouldn't have known any of that stuff existed if an intern ran his account for him.
He's made a recent pinned comment responding to fans' suspisions about a Dethklok poster being AI generated (for an upcoming LATAM tour), showing he actually pays attention to what others are saying, even standing on his statement on supporting real artists. An intern-run account usually wouldn't give any response whatsoever.
So yeah I found that blog post kinda weird for claiming that. Don't go looking for it ofc, it was originally about fandom controversies n shit
