An online petition (or Internet petition, or e-petition) is a form of petition which is signed online, usually through a form on a website. Visitors to the online petition sign the petition by adding their details such as name and email address. Typically, after there are enough signatories, the resulting letter may be delivered to the subject of the petition, usually via e-mail. The online petition may also deliver an email to the target of the petition each time the petition is signed.
The format makes it easy for people to make a petition at any time. Several websites allow anyone with computer access to make one to protest any cause, such as stopping construction or closure of a store. Because petitions are easy to set up, the site can attract frivolous causes, or jokes framed in the ostensible form of a petition.
Online petitions may be abused if signers don't use real names, thus undermining its legitimacy. Verification, for example via a confirmation e-mail can prevent padding a petition with false names and e-mails. Many petition sites now have safeguards to match real world processes; such as local governments requiring protest groups to present petition signatures, plus their printed name, and a way to verify the signature (either with a phone number or identification number via a driver's license or a passport) to ensure that the signature is legitimate and not falsified by the protestors.
There are now several major web initiatives featuring online petitions, for example Change.org, Avaaz.org, and 38 Degrees. These are growing in popularity and ability to achieve political impact. The Economist commented that Avaaz has had "some spectacular successes", but raises questions about what objective measures can be used to assess "the reach of a global e-protest movement". Recently, several petitions on Change.org have been attributed to the reversal of a United Airlines Dog Policy.
Some legitimate non-governmental organizations (NGOs) shun online petitions. Reasons include the paucity of examples of this form of petition achieving its objective. Critics frequently cite it as an example of slacktivism.
