What bothers me is the whole "opt-in" rather than an "opt-out" clause. If you opt-in (you want your porn, kink, fetish, eroticism, etc. in the privacy of your home), bet you dollars to donuts, your name goes on some dirty little black list somewhere in the annals of bureaucracy. Which then later gets to be called forth as evidence for job applications, credit reporting, criminal allegations, and so on.
Oh look, someone accused you of sexual harassment, and you opted out of the national porn filter, you must be guilty. Oh look, your soon to be ex-spouse wants the kids and you opted-in, you must not be a fit parent, you perv. Oh look, you want a job as a teacher... cop... minister...
Yeah, I agree, welcome back to 1984.
