I did it for a while a few years back more public cyber sites/progams with a bunch of randos. It was fun. I'm not sure how many played along, though got quite a few guys to go on cam. My favorite game was trying to see how many guys I could get to cum in a day. I think my best was like 4.
Eventually I tried to be upfront, but that didn't work nearly as well as just pretending from the beginning. Then I moved onto Second Life for a short while to try and find some teen rp, but missed the height of that scene. I actually started to have like friendships, then I'd feel bad, pathetic and sad. That also made me more scared about getting caught so I quit altogether.
I used screaming bee.
