Someone on Deviantart once tried to commission me a "pencil sketch portrait" (aka the thing I said I would do for the cheapest price, just $5, no background included)... and then they sent me a full body photo of a woman dancing in a room with like a thousand of butterflies flying around and asked me to draw that. As in, the whole freaking thing, not just the face. I politely told them that nope, that wasn't how it worked, if they wanted a full body picture with a background and additional details the price was going to be a lot higher... they never replied. Six months later, they showed up again to send spam/phishing links to my e-mail. Still not sure if they got hacked or if it was a scam all along :'D
