@daydreamerhoneyy its likely one or several of these reasons
- he suspected to be transpobic. He hasn't spoken out about jkrs transphobia and liked one of her transphobic tweets. Not speaking out against jkr is problematic because he has a large fanbase/followers and speaking out in support of the trans community would only be a positive thing. About the tweet, he unliked the tweet after people were calling him transphobic, many people say he liked it accidentally but that is unlikely considering he only had 70ish liked tweets at the time.
- I have never watched his livestreams but apparently he can be a bit inappropriate especially considering his fanbase is largely made up of minors
- someone asked for pureblood written in his handwriting for a tattoo and he did it, I'm sure you can understand why that is a bit off
- there are possibly other things that i can't think of at the moment
