I tend to target those that have a fetish for being ripped-off or scammed.
For one, I love the fact that it's very time efficient. I get all the money up front with no real promise to do anything in return. We like that.
But mostly, it's nice knowing that I'm genuinely fucking these poor guys up for the foreseeable future. I had a sub last year tell me that he had to get out of his lease agreement (for his expensive car) early because he sent me over $10,000 in a single month and it put himself in a financial hardship.
While this scene is almost never exciting for me, these instances of self-destruction for me are actually quite hot. I love knowing that dumb, pathetic, weak men will cripple themselves financially all because I decided to put some of my hot thoughts on the internet.
The best part is that it also works to pad my savings account even more so.
You dumb fucks just can't get enough of paying people that are already vastly superior to you in every way. The only thing I truly need to do is be available to accept your money.
