With some obviously fabricated information, and it was accepted:

Clicked Submit and…

Makes you wonder if there any checks and balances in place to ultimately discard my signature? What’s to stop some Brady goons from signing their own petition with made up names, or even more cleverly using address information out of the phone book or readily available online.  With minimal web programming skills a program could easily scrape the internet for valid addresses and automatically submit them to their little web application.  At the very minimum I find it surprising there was no zip code validation in the form;  55555 isn’t even an Arkansas zip.

I am now even less impressed by the 28,000 28,001 signatures they claim.

UPDATE: CREDO action, the company that is handling the Starbucks petition actually has zip code validation on their own site where people can sign the petition ( http://act.credoaction.com/campaign/starbucks_guns/ ).  There still isn’t any other validation.
