I think "a lot" is a broad term. Seeing as there are thousands upon thousands of cam models in the world, "a lot" could just mean 100 of those models. The words I'm more wary of are "most" as that implies the large majority of models feel that way.
I doubt any models who are on acf feel that way, but I would still wager that there are probably a fair amount of models who dislike their regulars even though they pay them. With so many models around and so many asshats around I'm sure that there must be models who are willing to deal with the complete idiots of cam society for the money, even though they're internally rolling their eyes.
Personally I don't cam in a way that I allow people I don't like near me. I decided when starting camming that consistently dealing with people who are idiots and not saying anything about it wasn't what I signed up for. I probably lose money because of this attitude, but I don't care.
When I speak to friends about camming, most of my female friends seem to hold this attitude that they'd feel this way about members. It is a preconception, but seeing as a lot of models don't make it past the first 3 months, have all of those models really lost those original preconceptions of members?
I think though that it'd be very hard for a full time model who's cammed for a fair amount of time to feel this way. Seeing as a large amount of models never will cam all that much or for that long there probably are a fair amount of models who do have very negative feelings towards their members, more than just an occasional "god you're pissing me off".
As much as ACF seems to be filled with a load of brilliant, clever AND kind hearted women, who all seem to have very healthy attitudes towards members, it doesn't mean there aren't a bunch of really nasty camgirls out there. I mean come on, statistically not all people are that nice, take members for example, I get dudes trying to scam me/say crap to me left right and centre, there are lots of them out there, just like there are lots of asshat members out there, there are lots of asshat models. Fortunately it doesn't seem to be a majority, I hope it's a minority! But because of numbers there are still a lot out there.
This is why members should just stick to ACF girls
