Base Claim:
1. A computer-implemented method for preventing spam emails from a share site, comprising: receiving registrations from users to set up share sites by a network-based computer system, wherein the users become owners of the share sites; enabling the users to send emails to invite people to become members of their respective share sites; receiving uploads at least one image or video clip from the users by the network-based computer system; storing one or more spam detection rules in the network-based computer system; detecting potential spam emails among the emails sent by the users based on the one or more spam detection rules by the network-based computer system; storing one or more false alarm reduction rules in the network-based computer system; automatically detecting, by the network-based computer system, behaviors of one or more senders of the potential spam emails at the share-site; identifying false positive emails in the potential spam emails based on the one or more false alarm reduction rules and the behaviors of the one or more senders of the potential spam emails at the share-site, which comprises at least: determining if the one or more senders of the potential spam emails have uploaded at least one image or video clip to the network-based computer system; removing false positive emails from the potential spam emails to produce a list of verified spam emails; identifying a first sender of the list of verified spam emails as a spammer; and prohibiting the spammer from sending emails from one or more share sites owned by the spammer at the network-based computer system.
