When a model works for a studio, their payment agreement is with the studio not the site, so it is 100% on the studio to ensure that the models are paid on time regardless of if the payment from the site has come through or not.
If he dosnt know how long payments take, how to cash out of a site, how any of this works then he's not in a position to run a studio in the first place.
Yes! 100%, you dont start a business without capital, running a studio is a business, you need money to be able to pay models, pay for replacement hardware as it's needed. Say the laptop / computer breaks, needs repairing, but he dosnt have any capital when opening the studio, what's he going to do then? tell the model sorry I need you to work for free because I need to fix the pc.
Let's say your account got hacked, you lost all the tokens on the account, you still going to pay your models?
This is why you dont start a studio with $0 in your pocket, shit happens and you need to be able to cover it.
When I hire people to do a job, I pay them what they are owed, regardless of if the end client has paid me when it's time to pay them. They did the work, they get paid, on time, end of.
A better question in regards to people braking the rules is, why did they and why was it allowed to happen, if a model is braking site rules then normally that comes down to poor training, which again lies at the studio. Let's say she knew the rules, she broke them anyway, then it becomes a question of what's in the contract, since that would have the details on how that situation would be handled. If he wasn't smart enough to make a contract, if there's a record of the model earning that money then the model needs to be paid, call it the expense of a lesson in how to run a business.
