Facebook may need to tweak some policies if it wants to stop the number of members of “The Official Facebook Petition to ban the inviting of friends on Applications” from skyrocketing.

The recently created group has hit over 1 million members, all requesting that “no (Facebook) application ask or require [them] to invite [their] Facebook friends to anything for any reason.”

The problem is simple: Each time Facebook users adds one of the profile-enhancing applications, if they aren't careful they can send it to all of their contact list, who will receive an unsolicited invitation to add the application.

The growing number of unsatisfied Facebook users–the group added 115,000 members in a week–prompted the company to react quickly.

Facebook wrote on its company blog on February 20 that several improvements had been made to prevent this and other abuses by applications.

The social networker fixed it so that when one gets a request from an application, it is possible to block the application directly from the request, which will stop it from sending any more requests.

Also, a few weeks ago, Facebook added the “clear All application requests,” which allows users to get ride of all unsolicited requests and invitations.

“It’s a good start, but not good enough,” wrote Adam Werlinger, the group’s creator as a response to Facebook’s attempts to solve the problem.

The group’s ultimate goal is to persuade Facebook to grant users the ability and privacy to block all application requests.

Until this is done, Mr. Werlinger, who believes that Facebook only listens to groups in mass, continues to urge Facebook users to join his group to “let Facebook know and see we are unhappy,” he says on the group’s site.

To add more weight to the petition, a protest is scheduled April 1.Werlinger urges the million-plus members to call Facebook on that day to “tell them what you think about apps.”

Facebook is the No. 2 social-networking site behind MySpace.
