For the curious they ended up fining them
£1,050,000 for
failing to provide accurate information in the end. Does make one wonder about the liability mentioned earlier. Ofcom felt they should have detected the inaccurate information (it took them 16 months before it became apparent), but it's not clear how it became apparent or indeed if it was possible for them to know it was inaccurate before they "found out", I think possibly they could have - reading between the lines (since they then adjusted the age level). That would have been quite interesting to know a bit more of the detail.
I don't think a webpage with hyperlinks falls under the remit of the OSA. Otherwise literally every website hosted in the UK and every website accessed by a "significant" number of UK citizens would be cover, no matter if that was Amazon or Wikipedia, a random blog, someone's homepage about their cat. Odds are there will be a hyperlink on that page somewhere. So as far as I can see a "dead" forum where all user-interaction has been removed (and I suppose ideally user login) wouldn't count since there could be no user to user interaction. However I am not a lawyer so may well be wrong.
