my ex always used to run ads that mentioned Come. anybody that responded saying they loved Come was usually good for making some interesting music. i think the key with that is to throw out an amazing yet quasi-obscure band. people that bite on that may be winners.
Picking which bands to include in an ad is an art form. Never include pseudo-famous awesome bands like Fugazi or even Shellac, because in addition to cool peeps, many people with absolutely no musical taste or ability have heard of them. Even if your list of influences includes 8 other obscure bands, weird people will latch on to the one band they recognize and think "perfect match!" The last Shellac "fan" I played with could not play a bass line unless it involved hitting an open E string every other note. This was... limiting. Other do-not-include-even-if-you-like-them bands include "Sunny Day Real Estate," "Sonic Youth" and "Pavement."
Some day, a dummer will respond to an ad mentioning "Long Fin Killie" and I will rock the world.
Also, include negative keywords. I used to put "no fans of Dave Mathews" on my ads at school, which I believe saved me countless hours of pain. And never play with a guitarist who sites "Stevie Ray" or "Hendrix" as an influence.
