@ Midnite: Basically a good idea, but there are always the ones who donīt even bother to look at peopleīs profiles before bursting into chat and without any hello or other polite niceties start to PM whomever who might fit their prey pattern...

As for the rest, I agree with Annie, last but not least because there are people here for which it could create problems in real life if their likings became known (whatever the reasons for that might be).
