the organisation hosting this petition is Change.org based in the USA - before signing it read the organisation's 'Privacy Policy.' My understanding is that your e-mail and details are accessible to anyone - according to the site 'Your support can be made public.' Be wary!

Gamification is still a popular avenue for doing this, but the likes of Yougov, Change and 38degrees all make considerable revenues from selling and aggregating data.
