For complete information on how member bans work, and the member bans main page, see Members: Bans.
User Name
Enter the user name of the member that you want to ban. The user name is everything to the left of the "@" symbol in the email address. For instance, if the member to ban has an email address of Jane_Trouble@example.com, enter "Jane_trouble" in this field. Note that you can enter names in any case, but they are saved in lower case.
Only the user name portion of the email address (jane_trouble), should be entered, as members cannot be banned on their actual name, only the user name portion of their email address.
The User Name field must be blank for "Always Accept" bans.
Domain
Enter the domain of the member that you want to ban. This is everything to the right of the "@" symbol in their email address. In the above example, you would enter "example.com". The domain name can also be entered in any case, but will be saved in lower case. To ban a top-level domain, enter it without an initial dot (e.g., net)
To view the next two options, click Advanced.
Type
There are three types of bans:
1. Always accept
2. Conditionally accept
3. Reject
If an address matches an "Always accept" ban rule, it is accepted with no further processing. Addresses that do not match any "Always accept" or "Conditionally accept" ban rule are rejected.
Records found in "Conditionally accept" will be accepted if no explicit reject information is found. Records found in "Reject" are rejected automatically, if matched. See Members: Bans for more information about ban types.
Applies to
Set the list, site, or server, that member ban applies to. The options you see here will depend on your privileges, whether you are a list, site, or server administrator. For example, if you are a site administrator, you will be able to create list or site bans, but not server bans. The Applies to field defaults to the current list.
For information on how to specify one server to handle all banned members, see Utilities: Server: Server Settings: Advanced: Global Ban Settings.
