Wow! 170 surveys a month!!! I've never even been able to get a big bonus 10-14 surveys is the most I've been able to do and I don't do any other site. Up until recently, I've used only 1 email for me and DH, but there was a thread a few weeks ago that said if you changed demo (me and DH) you had to use a different email. I also changed my gmail and have used the new one, but for me (and I take the majority of the surveys) I use my main home email. That is the one that I signed up for SR with, and I've had it for 10 years. I am so sorry that this is happening. Why does SR always seem to get singled out for these types of things? SR is such a nice honest site with great people.
I hope this all gets straightened out soon.
