@randarrington I think, and I might be wrong, that by getting an artist to create art they tie them to the scam more efficiently. If you spend time creating something that you're proud of and that you've incorporated in your dreams, I think that makes you less likely to pull back even when the red flags start flapping. So normally, if someone you don't know asks for your bank details, or asks you to return a surplus on some accidentally too large cheque, you wouldn't do it. But if you want to believe that the person asking you to send money their way is going to help your art in any way, you might chose to ignore the red flags and send money anyway. I think ths is why the commission scams are so effective...
There is also a reason why the letters are misspelled and unprofessional, but it's not because the scammers don't know how to spell. It's to weed out the least gullable people at an early stage, so that the next part of the funnel gets people in it who have displayed a willingness and a tendency to overlook red flags, which, from a pure business perspective, is a very good way to up their conversion rate and spend most of their time on people more likely to fall for the entire scam. It's cynical and disgusting all the way down.
