Well, add me to the list. I am so sorry. I too use different email addresses. I guess I'd never thought about it, just switch it up different days. And I never thought about it not being right to do the surveys again if they came up.
But I only do surveys w/sunshine, except for one I tried the other day somewhere else. And I only work to get one a day. I was having so much trouble with OTX, that I pretty much stopped trying with them.

But I am so sorry
