Abstract

A system and method to control sending of unsolicited communications over a network is provided. Typically, the network is the Internet and the system defines a SPAM prevention tool for users of an on-line service, such as an on-line bidding service. Users may contact an intended recipient with a contact form, which is forwarded to the recipient'"'"'s e-mail address by an on-line service provider. A link accessible from a Web site allows recipients of unsolicited e-mail to complain to the on-line service provider. Sanctions are implemented against the sender of unsolicited e-mail based on the frequency of complaints. When the complaint level against a sender reaches a certain threshold, the sender is unable to use the contact form for a predetermined time period.

Claims

1. A method executing on a hardware computer to control communication of unsolicited information in a network, comprising:

enabling a first user of a network-based system to initiate a communication with a second user of the network-based system without the first user having access to contact information of the second user, the communication to be related to one or more items listed for sale by the network-based system;

providing a link to enable the second user to cause an electronic complaint form to be generated, wherein the electronic complaint form is to enable the second user to report a complaint against the first user when the communication initiated by the first user is not related to the one or more items for sale by the network-based system;

receiving and storing information associated with the electronic complaint form; and

associating the complaint with a user identifier of the first user.

2. The method of claim 1, further comprising:

responsive to the first user initiating the communication with the second user, generating an electronic form to receive a message to be transmitted to the second user without the first user having access to the contact information of the second user; and

responsive to receiving the electronic complaint form from the second user, determining one or more actions to be applied against the first user.

3. The method of claim 2, wherein the actions to be applied against the first user comprise one or more of sending the first user warning messages, sanctioning the first user from communicating with the second user, and preventing the first user from using the network-based system for a period of time.

4. The method of claim 1, wherein the first user and the second user are known to one another based on the user identifier of the first user and a user identifier of the second user instead of contact information of the first user and contact information of the second user.
