That or I believe other family members step in and tell them to cut him off. There is no doubt in my mind his extended family knows what kind of fuck Phil is and how despite being 37 years old, is still money sucking leech attached to his parents. Aunts, uncles, nieces or nephews would no doubt see this and possibly intervene to try and get them to close their wallet.
At the end of the day, his parents are just another pair autistic wheelchair fans who don’t even watch his content and still blindly throw money at him.
