Usually a "sub" game (like $5/mo) gets you on voice comms w/ the streamer who has their web cam enabled so you can see them on stream.I'm not a gamer, so I don't know - but do you actually see the person you are playing with, or is it a pic or avatar? I ask because I wonder if you are paying for a real live girl or anyone who just posted an ad with an attractive picture?
Difficult to get "catfished" on larger streams where the personality is a known figure. Probably happens occasionally for smaller things but a webcam makes it a lot more difficult to fake (atm)
It's an.. interesting culture lol.
