Paid to Sign Political Petition?

Technically it's illegal to offer people payment to sign a political petition. But here's a twist...what if the payment is just a few "points" toward an Amazon bonus card, not enough for the signer to buy anything, but enough to help people who use paid blog/chat sites to cash in on their content sooner?

This web site is actually in favor of more and better public transit, but thinks that, in view of the sorry state of the federal budget and the burden that's likely to be passed down to states and localities, public transportation providers should be trying harder to get funding from the community rather than from government.

I'm filing this one under "Scam" because, although it may offer legitimate Amazon points payment and some judges might pronounce it legal, I think it needs ethical investigation. At least, if this is ruled legal, paid blog/chat sites should start bustin' out all over with petitions representing other points of view...such as petitions to reduce federal spending, even on things everybody likes.
