One of them was from a girl who called herself "Topanga". This was her character/fursona name. She lives/lived in Nevada. Basically she had me do a character picture of hers (pin up), and said she sent a check in the mail. I was young, and naiive, and being it was a friend (over the internet though), I trusted her word. It's been 7 years now, and I STILL haven't seen or heard from her, or the money she owes me. Naturally, after the first year I gave up. I heard from her 2 years after I drew the picture.. said she was going to send another check. Stupid me though, sent her a scan of the image before I received the check. I guess you live and learn, right? I don't know if she's buying any more artwork from other artists.. but if you know anyone by that name, chances are, she's going to try to be your friend first, and cheat you later. :/ ..
The second one I was *very* careful on, and turned up someone random over the internet. I was in a chat room, when he saw my website. Wanted to get to "know" me, and get me to do a drawing for him. Told me he wanted to see a very very rough sketch before he gave me the full amount. I didn't trust him from the beginning, most especially when he INSISTED he send it to my HOME address, instead of elsewhere (that's right folks, I DON'T send things from my HOME address). Needless to say, I sent him a very very very very unusable by even the great artists of the past themselves, sketch to get a general idea of what I could do.. he liked it, but didn't like the fact I wouldn't give my HOME address so he could send me a money order.
So I guess my advice to those, would be DO NOT get pressured into a sale.. no sale is worth it. If you feel you're being pressured into anything you don't feel comfortable with, DON'T DO IT. And never ever send an image or copy of a commission before they pay. -.-; But that was already nicely put by Limey about getting the dough up front. I was fortunate, but I know there are many out there that aren't so.. :( .. In such respect, I'd personally like to apologize, I've never done anything, nor do I plan to.. but no one deserves to be "scammed", "cheated" in any way.
