I'm not generally a distrustful person, panda888 - but how come you created a new account to post this comment?

Maybe you could post a little bit of background info about yourself and your lack of connections to Yell to avert any suspicion that you're not a genuine disinterested individual.

In any case - from my memory there were stories about this in the mainstream press. I can't vouch for their veracity but if you bother to reply then I'll try and find a few references.
