I started doing point commissions, because I never felt right about accepting money for drawing copyrighted characters that I don't own... and back then, it was easier to obtain points for premium memberships, like 636 points would get you a three-month premium membership... but they eventually did away with that option, and they made it even harder to obtain a premium membership (I think now, the lowest option you can get is twice as many points for a 1-year premium), and it's hard enough to obtain points. I've opened donation pools and done point commissions, and I know other friends on dA have done the same, but the feeling of having these options taken away from us is frustrating. Being on dA for almost seven years, I feel I should have had at least four year's worth of premium membership by now.I've had enough "gimmee!" requests that I have a standard answer: Sorry, I don't have the time to do freebies. However, I am open to commissions. One person actually asked what a commission was, and when I answered that it was a request with dollars backing it up, they said, "oh nvm".
But yes to all of the above, there are all kinds of weird and strange fetishes on dA, I haven't seen much of the diaper fetish (or, not as much as others), but I've seen obese fetishes, vore fetishes, perhaps the strangest fetish I've seen on dA is one guy who has a fetish for surgical masks... I don't get it. And there's one guy who always has Timmy Turner drawn being sexually assaulted by any female cartoon character you can imagine (he's gotten nearly twenty of these commissions from one artist alone). I get fetish requests from time to time, but whenever I do, I turn them down. I remember a couple of years ago when people kept wanting me to draw more of Jenny Foxworth from OLIVER & COMPANY, I had a couple of requests to expose her underwear... uh-uh... the last time I drew a character in her underwear (in a comical situation, mind you), that resulted in a week-long controversial feud.
