I remember maaany years ago when I was using Webcash for processing....
I knew a tech fairly well, he was a good shit. He told me they were processing for a gay single male site and this dude was pulling in over $60k a month. On his own. Pretty good coin if you ask me.
If I remember correctly, it was primarily a cam site. Cam in the shower, cam in the kitchen, cam in the bedroom. A novelty many years ago!
