50 mypoints for a survey (I think of it as 25 UA miles) is so much less than any other reputable surveyor, like e-rewards or opinionplace, that I've never put much stock in them anyway...

If I ever click on a survey I try and pre-disqualify myself by being too honest-- work in marketing, did every survey known to man in the last 6 months, etc. 10 mypoints (5 miles) MIGHT be worth an early disqualification, but not anything more to me.
