Blacklist

When a Publisher deletes and blocks comments or trackbacks, the originating IP address or hostname of the blocked item is added to the Publisher’s firewall settings. The Publisher can see the list of blocked hostnames and IP addresses in their firewall. All IP addresses and hostnames blocked by all Publishers are tracked, and will be compared against the blogging system's global blacklist.

Blogging system global blacklist

The blogging system checks for IP addresses or hostnames that have an unusually high number of visits per day, indicative of a Spam BOT. These IP addresses and hostnames are added to the global blacklist automatically.

Spammers and visitors who are blocked from the blogging system will receive an Access Denied message.

Blacklist blocking happens if ...

- post contains a trackback URL that is on the blacklist

- comment contains a URL that is on the blacklist

- comment originates from an IP address that is on the blacklist

- blog is accessed from a blacklisted site

Blogging system global whitelist

IP addresses and hostnames of key sites (for example, Google.com) are added to a whitelist. This action ensures that these sites are not blocked by mistakenly being placed on the global blacklist.

Global keyword list

The blogging system maintains a spam keyword list. This list contains all of the typical spam words and is updated as the spam-world evolves. All trackbacks and comments are checked against these keywords as part of the automatic spam trackback and comment checks.
