If it is indeed SuperHound who's been doing the copyright strikes against detractor channels, than this is simply karma. It's almost like having a rabid dog who'll bite at anything that smells like a detractor ends up painting a target on your back as well. Phil may not have directly been flagging these channels (or he very well could have for all we know, you can't believe a word he says), but I'm sure he at no point took SuperHound into his Discord that doesn't exist and told him to calm the fuck down...and now we're at the natural conclusion of antagonizing a community that already hates you.
If it's indeed because of a music-related copyright strike, then Phil's just a plain idiot. He's been on YouTube for how long now and STILL doesn't understand how strict YouTube is where copyrighted music is concerned? Why would you even risk it for a video that maybe gets 2k views? Stick to your shitty fan-made pre-stream music and don't risk a strike by using licensed music. Lastly, it's funny how it's a tragedy when what's been happening to detractor channels for weeks finally affects him. Now it's a career-ending apocalypse and he did nothing wrong. Nothing a good old fashioned raising of funds stream can't fix I'm sure.
