EU parliament accepted a last minute amendment, mandating age verification for pornographic (whatever that is) content online, punishable with up to one year prison sentence.
This was rolled into a directive concerning CSAM. Because adults accessing porn need to be de-anonymised to avoid child exploitation?
Assuming it’s based on this EU prototype:
They don’t know why it was requested, but do know who, where and when.
So they gather the logs of A, the token provider. Is the target present? They have his token. They also see where and when the token was used. Did you have a fun time yesterday evening, on your phone at home, on websites B, C and D?
Next up, if they want even more detail, gather the logs of B, look for the token.
