Content warnings are dumb enough but the worst thing is that in that middle Facebook post, his sentence about the content warning is actually longer than the content he was warning about. At this point he's just got used to saying it and thinks it makes him look considerate but of course it doesn't.
I think people are right, in that Phil constantly threatening suicide has put anyone off who would have tried to help him in the past. You don't have to be a genius to see that he cries suicide for sympathy, attention and nothing else. Besides, it's hard to buy someone as depressed when they upload videos of them sitting and smoking with this smug wannabe tough guy look on their face while bragging about how cool they are.
