They seem to throw a bunch of surveys against the wall and hope one will stick. I have been told that I am a match for a survey when it has no relevance to my specialty more times than not. Once in a while I qualify for a survey but more often than not , I get a "Thank you but you are not a match for this survey." Lots of emails deleted, usually 15-30 minutes/day spent in finding out whether or not I fit a particular study. Not making much money off of this for the time spent.
