I had to deal with some guy at work trying to do some tiktok video and including me in it so I could complement his side gig or some shit (and likely only including me because women get views). And if I complain too much about being included in their grift everyone will shit on me for being a karen or for not helping him with it. Jesus fucking christ, I hate people that try to constantly plaster their face and name on everything to make money. Fuck youtubers, fuck tiktok, fuck ads, stop stealing peoples work for a quick buck ‘by doing commentary’, leave me the fuck alone
At a random time, when nothing is happening, hand him a “paid talent release form”.
If you look up “talent release form” it’s what allows a creator to use materials with another person. As it stands now, he asked you to participate but did not have you sign a release (with no fee), so you own partial rights to income from that video.
Say to him: “Since you are a pretty big creator I assume you’re familiar with releases. I grabbed a standard one to give you rights to my previously included videos, and here’s another for any future videos including me for a 50% share. I’ll sign them after you approve and sign unless you have a standard set you would like to use”
This makes it a business transaction, vs a “leave me alone”. He won’t want to figure out how to pay you, so he’ll probably stop.
