I don't understand how this makes it to Top News. I think at this point we are all well aware that no user-password store is impenetrable or invulnerable and porn websites would hardly be an exception. If you do not know by now that you should not be using the same password across multiple accounts, it seems like there is little hope. There is no lesson to be learned here. Is it not an implicit assumption that if you subscribe to a porn website someone is mostly likely going to find out one way or another?
1. Don't reuse passwords.
2. Don't subscribe to porn sites if you have something to lose from someone finding out.
