Anyone notice this with QuickThoughts?

So I am using 3 different platforms.. QuickThoughts, CrowdTap, and Qmee. I stopped using Qmee awhile ago, so let's not count that. For the past month or so I stopped using QuickThoughts. Only CrowdTap.

I used to get 20 or 25 emails in my spam per day, now I get none. I attribute this entirely to QuickThoughts since it happened once I stopped doing surveys there.

Anyone else notice this?
