You guys complaining just don't fit the profile the company issuing the survey is looking for. It's simple....it's not anything else.
Get bitter all you want that you aren't just having free credits thrown your way like beads off a Mardi Gras float, but you have to fit the corporation's pigeon hole to get the credits....and you can't just blow through the survey clicking random answers, either. Maybe you, OP, aren't doing this, but many are.
I haven't missed but one or two surveys all month this month. And, it isn't magic. I just happen to be in the demographic they are looking for.
If you think you are blind with frustration now, try signing up for survey sites (about 12 of them) and watch your email inbox fill with survey offers. Now, try and qualify for 50% of those. Rejection is part of the game/life. It just is what it is. Move on and invest your anger somewhere it will actually have an effect.
