Laws are changing regarding on-line pornography on sites.
If you provide pornography to people in the UK on a commercial basis (ie for money) then you have to introduce a proper age check system.

On this site, we don’t. We blog about adult matters, provide links to interesting sites (well, we hope they are interesting) but we are 100% non-commercial. While the sites we mention often (usually) carry advertising, we try to check that they are ‘free’ in the sense that you do not have to pay to see what we have linked to. Ourselves, we have no charge, not even any advertising.
