It sounds better on paper than I imagine in practice there's a LOT that could go wrong.
The main issue is you're professional workplace is also your living place as well as your roomates. Also you can't really put professional stipulations on a housing lease. What if you're a 8 hour scheduled model and the other is 'so so' logs on for an hour then spends five hours wanted to gossip with you about all the terrible things that happened in that one hour? What if they bring over that 'creepy' friend you don't want to be naked around even if there are doors in between you? If one of you has a stalker problem you BOTH now have a stalker problem.
These common profession arrangements work because 'work' isn't being done in the living space.
I'm just being devil's advocate on this since nobody really seemed to be weighing any pro or cons on this.
I agree with Caireen on this, stuff like this happens with any room mates you have. I actually think a fellow full time camgirl would be more sensitive as they share the same issues and fears. It really depends on the housemate, but I've had two housemates before who I had while camming full time, both of them frequently brought people back which could have been a safety issue for me. My male housemate brought over a guy who raped my friend in my bathroom when she was drunk, and despite me telling the housemate this and him believing me, he still couldn't work out how to tell the guy (he was a co-worker) that he wasn't allowed over when he invited others round, so I continued to occasionally have a known predator in my home. Me and my housemates now continuously end up having great conversations in the kitchen when we should be studying, and one housemate starts not so exciting conversations which are nearly impossible to get out of. And the stalker issue, well camgirls having a full blown stalker is still pretty rare. I mean it's common in the cam world overall, but still pretty unlikely, and you're probably safer if you're all together and completely aware of the situation, and I imagine you would all be reasonably vigilant about your security, which a non camming housemate would not necessarily be. Plus, stalkers tend to choose who they stalk, they will sometimes move onto another person, but if they're obsessed with one girl it doesn't necessarily mean they'll start obsessing about another just because she lives there.
The cons I would say are the same as moving in with anyone. Don't just move in with anyone, you should know you would work well living together. As Kate pointed out, picking people who you get along with super well isn't always the best as it could lead to more procrastinating rather than work, so I guess it needs to be a good balance of getting on well, but also encouraging each other to work rather than skipping off.
I think though that living situations are generally better with people who are living a similar lifestyle. Like if you're a student it's best to live with other students because they understand that home is also a study space, but also have more similar hours to you so will be more tolerant of certain student habits. Same as if you're a professional working 9-5, you wouldn't necessarily want someone working shift work, always coming in late and cooking dinner, going out during weeknights and then having their work nights when you want to let loose.
The guy in the room next to me is a twitch streamer and because I cam it doesn't bother me as much as it might bother someone else, because I know that there will be days when I'll want to cam and I'll make noise chatting or doing shows. Granted it's a bit more embarrassing making sex noises or talking about sex than him chatting on about his room viewers and whatever game he's playing, but I know that if he ever complains I can point out that he often streams until past 1am. So I think with that in mind I would much prefer to live with other camgirls.
The main con of living with other camgirls I think would be that if they were bitchy or generally not very nice people then they could really fuck with you. I have heard some pretty awful stories about some of the UK girls trying to cam together (ones I don't think cam anymore but were once pretty successful). I cannot remember exactly what happened but it sounded like a few of them were a bit insane, which isn't unlikely seeing as the nature of camming or really any kind of sex work tends to draw in some crazy ladies. I guess there is that if the girl was nuts then she could share some awful stuff about you, I have heard of this happening before, and she could easily put your life and livelihood in jeopardy. If she were successful it could also cause a lot of hate. They would know a lot about you, your sexuality, whether you have a partner, maybe about your parents, things you like, they'd even likely know all about you complaining about that regular you actually love but who sometimes gets on your nerves. I mean, that's a lot of information if it went south. I've lived with a crazy girl before who would have been vindictive enough to do this sort of thing, fortunately she didn't ever start camming so she didn't have any information from cam to use against me, but she did make camming nearly impossible while I lived there.
