I've created a http:BL implementation for Drupal, called httpbl.module. httpbl checks if a visitor's IP is listed on the http:BL-list and aborts the request if that's the case. http:BL contains IP addresses for email harvesters and comment spammers. Together with this module it could cause a substantial decrease in comment spam on Drupal sites.
This module will make the integration of the existing user database and profile images with userplane web chat. You need to register first on http://www.userplane.com, after registering you will get a mail from
userplane team, this mail will have all the information on how to setup your account on their servers, then you can use this module to integrate your database with the web chat.
