Edit: to clarify why it is different... a camgirl has a limited audience of a couple of hundred people and she doesn't have the time or the budget to make 1000s of videos a month with dozens of actors and actresses. Most models can't even fit into multiple niches, so unlike the porn producer the ebony model can only make ebony videos. Sure, she could probably squeeze in some fetishes if she is into that, but her capacity to shoot videos and sell them is really minuscule in comparison.
A porn producer usually will shoot thousands of videos every year with hundreds of different actors/actresses for different genres and sell them globally. They can lump old videos together because they keep producing fresh content at a faster speed.
Cheap camgirls have existed forever, but they were usually low camscore ones. So a member knew that when they purchased a video for 50 tokens they were purchasing it from a low camscore girl, that if they wanted videos from the girls on top they had to spend more. The majority of the models on top, for the past three years at least, have kept their videos a bit more exclusive asking around 200 tokens per video (this was the reality with Aspen, NikiSkyler, Ginny, that generation). But now there is a batch of new models on top with really high camscores giving out their content almost for free. I get it, if you are so careless with your content that it is available on every porntube, you know there is not much of a reason for a member to spend more than 5 tokens for them, but when you offer them for next to nothing you are hurting the entire system. The people who get into your room don't always know why those videos are so cheap and they expect everyone elses videos to be on par with that.
Models like me (I am non-nude, and it is very expensive and difficult to get anything I make) have always depended on a handful of guys who value exclusivity. But in the past we could get a room going and a nice atmosphere because random people were willing to tip 100s here and there for games, raffles, and topics. Now they aren't even willing to spend 5 because they know those 5 could score them videos in other rooms.
The reason this is problematic is because the model who sells her videos for next to nothing isn't even making much out of it. How many videos do you have to sell to new tippers for any amount (usually 10 tokens) for it to add up? It makes no business sense for them, and it screws the entire system. It would be better to simply retire the old videos and make new ones than to damage the entire ecosystem.
