Look, ditch the bitch. You have already shown that no amount of money is going to satisfy him. If you give him $2, he's going to bitch about why can't you give him more. If you give him $200 he's going to bitch about if you can afford that much, why don't you give him more. You're being played for a fool by this asshole. Especially once he begins talking shit about you. If he has such little respect for his fans, especially the ones who give him money, then he deserves to lose his entire following and be blacklisted from YouTube. It's why I rarely upload to any of my channels. It's drama that I neither need nor want when you start drawing in the haters. Tell him off in very unfriendly terms if you want, and then abandon and forget him. It seems your asking our permission to drop him.
Well, here's my permission. Leave his channel behind and never return to it. Let him piss and moan and call you names. But never return to him for any reason. If you really want to hurt him, talk a a lot of people in the comments section and convince them to ditch his worthless ass.
