If you believe you have reached this error page erroneously, please complete the form below. To aid in resolving the situation, we need to know the name of your internet service provider. Other relevant information you are willing to provide, such as the time of your connection attempt and the city, state, and country you're connecting from, may be very helpful. While we don't want to invade anyone's privacy, if you know the IP number you're connecting through, that is extremely helpful. Any such information provided will be used _only_ for technical support and site security purposes.
Some of the immediate security measures we take to maintain the integrity of our system may temporarily affect the ability of some responsible users to connect to PetitionOnline.com. This is especially likely for a small fraction of AOL users, since AOL is functioning at the moment as a haven for vandals. Because some other ISPs, like ATT.net, share access points with AOL, their users may also be effected.
In the long run, we won't let a few miserable provocateurs ruin the free speech of millions of responsible participants at PetitionOnline.com. By calm persistence, together we will hold the upper hand over that tiny number of people who apparently can't handle the basic responsibilities of free speech. Don't let the vandals get to you, and let's not give them any unnecessary satisfaction along the way.
Thank you for your patience!
