If it's in the chit-chat section there's a fair chance it won't be relevant to many/most forumites. It's 99% certain it will have nothing to do with racing, which is as it should be.
There are countless threads I haven't looked at at because the headline tells me I needn't bother.
This time last year my new year resolution was take off ignore all those I had on it and, honestly, I'm glad I did as I've had sensible exchanges with some since then.
Personally I don't care what Ian's motive is for posting as he does. Sometimes I read his stuff through, sometimes I give it a paragraph and think he's had a dram too many 
Phil came across as a total moron - if you're reading this, Phil, keep reading - but I met him one evening in a pub in Hamilton and he came across as a perfect gentleman, admitting his alter ego was pure mischief on his part.
Ian's posts re Waitrose etc are harmless curiosities in which he doesn't insult anybody so I don't see any issues.
I do vaguely recall Ian from the initial days of the C4 forum (I think) and remember some minor spats but, to be honest, back then I was probably somewhat more spattable myself.
What's going on at the moment in these chat threads is nothing to fuss about.
