This is part one of the religious rights plan to go after porn sites and their patrons. Don’t give them your ID. If they get power, it will come back on you.
Not if you use a VPN. But now it wouldn't matter even if you were using a VPN because if you want any porn you'll need to submit a state-issued ID for "verification" purposes.
Im not sure ISP’s wouldn’t fight against turning that data over- and it would be hard to prove that it’s necessary for some kind of law enforcement access. (Unless they outright make porn illegal.) which would make it hard to acquire the necessary warrants (normally).
Whereas, it would be a relatively simple enforcement claim to say they need to see all that data to ensure PH’s identification compliance.
