Traceable access Logs?
... content providers should keep logs of access for a period of six months to a year to guarantee the BBFC could trace “every age verification to its original source”. Of course, Ageify is developing such a solution and is "ready to showcase it whenever needed”.
I can just see the round-robin household letters where the BBFC demands to know who accessed www.kardashianswithdonkeys.com on such and such a date, just because they have a record of that IP in their access.log files.
Perhaps Capita might get the contract to enforce access ...
