Ensuring the integrity of our petitions is vitally important to us and we put significant resources towards spam detection. We monitor all petitions, all the time - 24 hours a day. We have a multi-layered process of automatic detection and human investigation, and our staff is constantly evolving our tools and improving our systems to keep pace with potential hackers and spammers.
Like any online platform, Change.org is regularly targeted by would-be spammers. This spam can take many forms, one of which is adding fake signatures to petitions. This kind of spam is almost always caught before it goes live on the site.
In extremely rare instances petitions have been the target of successful spam attacks that added inauthentic signatures to the petition. In these instances our policy is to immediately cut off the source of the spam, remove the fraudulent signatures and bring the signature count down to its authentic number.
The Change.org community is a vital resource to us in spam detection. If you believe that a petition you signed or started has been spammed, please contact our Help Center immediately.
