( CNN ) -- Users have one week to vote on the proposed changes to Facebook 's policy , including the ability of users to vote on future privacy changes . Voting opened on Monday , and users have until Monday , December 10 , at noon PST to make their opinions heard . Facebook has put up a custom voting app powered by a third-party company for this vote , and the results will be tallied by an independent auditor . `` This feedback allows us to respond to your questions and make substantive changes to our proposals before they are implemented , '' Elliot Schrage , Facebook 's vice president of communications and public policy , said in a blog post announcing the vote . Facebook proposed the latest changes to its Data Use Policy and Statement of Rights and Responsibilities on November 21 . Users and privacy groups immediately expressed concerns over the modifications . In addition to a proposed end to public voting on these types of issues , Facebook wanted to change to how users control who can send them messages . Also , an addition to the Data Use Policy would allow Facebook to share data with affiliated business , such as Instagram . On Friday , two privacy groups , the Electronic Frontier Foundation and the Center for Digital Democracy , sent an open letter to Facebook CEO Mark Zuckerberg objecting to the proposal . `` Because these proposed changes raise privacy risks for users , may be contrary to law , and violate your previous commitments to users about site governance , we urge you to withdraw the proposed changes , '' read the letter . They also say the changes could violate Facebook 's settlement with the Federal Trade Commission , in which the social network said it would obtain consent from users before sharing their personal data with third parties , and provide users with clear notice when that information is shared . Facebook has a rocky history with privacy changes and resulting backlash from members . In 2009 , the site made previously private data such as friend lists and profile photos public by default . The following year , users were automatically oped into a new `` Instant Personalization '' feature that shared private information with outside companies such as Pandora . The outpouring of comments on the Facebook post announcing the proposed policy updates was huge . More than 20,000 people commented on the post , voicing concerns over the company 's proposed updates . `` I do n't want advertisers to have my information . I made this account back in 2005 as a way to keep in touch with friends , not be bombarded by ever increasing advertisements , '' commented user Nic Raines . In that post , Facebook also proposed to end public voting on changes to site governance . The voting option was first rolled out in 2009 in response to privacy complaints over a chance to the sites term of use . At the time , Facebook had just 175 million users . This voting app is a improvement over the previous system . Past votes just required 7,000 users to comment on an official Facebook post . Facebook said the reason it wanted to do away with votes was that the comment system valued `` quantity over quality , '' a problem the new system already seems to address . There are about 1 billion people on Facebook , not including bots or fake accounts . Facebook will require 30 % of those active registered users to take part in the vote for the outcome to be binding . If less than that percent vote , the company will take the results under advisement . Getting 300 million Facebook users to vote could be difficult , especially with the lack of viral appeal such as a fake lottery ticket . In addition to voting and commenting , Facebook users can join a live webcast on Tuesday , during which Facebook officials will answer questions .
