Appreciate your answer. Parts of your post make it seem like you have next to nothing to do with this; while other parts make it seem like you do have responsibility for this.

Also, it is not our company and operates completely independent from us.

Do you mean by this that the SaaS chat application deployed at chat.youporn.com is developed by a different entity to youporn? If so, then I understand the different entity part. But does that entity also own the users and serve its own TOS than you guys for chat.youporn users? If you are merely deploying a SaaS but have your own TOS and own the users, then it seems like while YouPorn may not be at fault for the technical goof up, but you are still responsible overall since the users belonged to YouPorn(not the parent entity).
