You made a very strong claim that she committed a sex crime. You imply her accusations are wrong and malicious. You jumped to that conclusion and took that as fact. And you didn’t even bother to read what she did. You judged her without even caring about that.
Not saying you are a bigot, but what you did was bigoted. You should reflect on your behavior, apologize and resolve not to do it again. Only then you could ask for the downvotes to stop lol.
Italy made VPNs practically illegal. The UK might soon follow. And surfing the web with a VPN is a painful torrent of capchas. And email addresses you can get without revealing your phone number to identify yourself are becoming sparse too.
If you’d want to actually address the issue (insofar unsupervised teenagers watching porn is an issue) you’d need something like a U2F security key that can be used as anonymous age verification and be bought anonymously in a physical shop for cash, just by showing your ID to a clerk (without your details being stored). Keys being stolen or misused could then also be flagged in a public database.
