First, this is so obviously going to be used against the LGTBQ community. Second it’s dangerous as fuck.
Third, if they actually cared about this they need to actually think about this rights restricting law. You could use browser attestation or APIs and not violate anyone’s rights, but our MPs don’t know shit about technology.
I’m not in favour of this option either, but it’s better giving the government a list of everyone who wants to access Grindr or buy a trans rights book, or read a forum about guns, or whatever other hot button issues the government decides is controversial.
Creating such a list is the most dangerous thing a government could possibly do.
Already implemented in my home state here in the US. I’m glad I am more tech literate and constantly run a VPN (as well as other privacy software) but most people don’t. These laws are so horribly invasive and open dangerous doors.
On what server side? If 1 in 100 sites asks for your ID, then you simply use the other 99 that don't. There are so many clones of different porn sites that don't give a single fuck about regulations, why would they care about that law.
If lawmakers won’t piss off and iPad parents keep demanding we protect their children from their own responsibility as parents, then we’ll get shitty laws about this.
