I thought I'd start with a few requesters that we should not hit because they either reject hits or put hits up that are crap.
Here's my list so far:
DO NOT HIT:
Scabl - cheap
Zachary Olander - gets you to enter personal info, rejects a lot
MIT Sloan School of Management - very long survey (1/2 hour plus for .50)
Erica B Slotter - don't remember, but was on my 'do no hit' list
Hellen Shurmer - this one just posted an easy $1 hit, probably screwed up on it, and then rejects me even though she screwed up. I'm still awaiting her email response to see if she will fix this (my guess is that she can't once it's rejected
