"A shortlist of pretty random stuff"(?) It's the worst search function I've ever seen in my life and that's the most puzzling admission I think I'll ever see. A search function that's set up to generate "random stuff?" That's worse than completely useless; it's intentionally misleading--unless you're saying, like when responding to a bid query, that your only duty under The Laws is to state the agreement with the user (that he clicked "search," and you returned...something) but not actual substantive search results. Do you guys not have an actual database of user names, perhaps including real names, if provided by the account holder in the profile?
