As I tried to explain above, having this sort of content available at all puts the entire existence of the site at risk. The credit card companies cut off PornHub, but don’t think they won’t go after content they don’t like in other ways. The credit card companies could threaten the hosting service or domain name registrar with a ban if they don’t drop EroScript. Those service companies wouldn’t hesitate to shut the site down because they can’t afford to piss off their primary method of collecting money.
A legitimate way you can help is to donate to the EFF, which is about the only organization that speaks out about this issue.
