I have a Virgin Media subscription for my phone and a while back I discovered that sometimes Reddit didn't load. It took me a while to figure out that it was on 4G and happened because I'd been using Virign's DNS servers. This is a similar "adult filter", that most UK ISPs implement. AFAIK the filtering isn't legally mandated, but something the ISPs decide on together based on a some government memo. In any case it's dead simple to bypass and a very blunt tool. For example, why does Virigin block Reddit, but not Twitter? Both sites feature adult content, in fact so does Google image search. The silver lining in all this stupidity is perhaps that it creates a more technically talented population. I don't expect most teenagers know or want to know about DNS, but if that's what stands between them and adult content I'm sure they'll learn.
