Personally i think you should continue doing skins mate, remember that what you're doing isn't charity. You should value your work and not listen to people who've done nothing in their life. Those are the people who don't understand that creators aren't charity workers. This is just an extra option to help you out financially and getting something out of it, to some it's nothing and to others it's adds a bit of fun.
Don't listen to people who are just out there to send hate, listen to those who support you.
We all know these broke fat fucks are just vicious because of their insecurities. Have a nice one mate :)
