Oddly enough last year I helped persuade ICO that Bluespam was not (as 
they first thought) prohibited - so they changed their guidance. A bit 
of a blow for freedom, but the law is the law.

That rested on a very similar area of interpretations.

I'm not arguing in favour of infallibility, but I'd also hate everyone 
to be chasing a red herring. Which bit of ICO guidance contains this 
particular guidance - I find their website very difficult to speed-read.
