Now that I think of it, maybe cows like Russell Greer are the reason for the influx of camgirls/titty streamers. As opposed to "old school" gigs like stripping, escorting, etc:
1. Never have to see, smell, or be in the same physical vicinity as a Russell Greer.
2. Able to receive monetary compensation from a bunch of simps at the same time.
3. Can apparently make money just by showing cleavage and appropriating SFW platforms like Twitch for the camwhoring - don't have to get fully nude, and maybe using platforms like Twitch works for guys who are worried about their mom asking them what they're doing on the internet - they can say they're just watching a "gaming channel" even if they're just there for the tits.
As lame as it is, from a financial POV, it seems like a better deal. Honestly, it wouldn't shock me if "old school" adult entertainment ends up going out of business in favor of amateur, social media models.
