reply to gaforces Blocking ad domains will prevent ads appearing in your browser. If that's all you care about you're fine.
It does nothing to stop your ISP from selling the total record of all your internet activity.
"Industry self regulation" might result in internet users being able to register for some sort of opt-out list - but then you would be giving the advertisers your information in exchange for an unenforceable promise that they will ignore or anonymize it. This also does nothing to prevent ISPs from selling user data.
