When you pay models to have sex and commercially exploit the resulting film, you have the moral responsability and legal liability to protect the health and safety of the models!

You are lucky it was just syphillis and not HIV! Just wait until someone claims they got HIV on your set, you are in for a legal battle that will take every single penny you have.

You are responsabile for everything that happens on your set whether you like it or not. If a model is injured on your set, you are legally liable and responsabile. That includes STDs, HIV, accidents, etc., etc.

It is a safe assumption that any model willing to perform bareback without a vaild testing procedure in place is already HIV positive. If they aren't already, they will be soon enough. And if it happens on your set, you will be held liable.

Good luck, it sounds like you are going to need it!
