This hack integrates the phpBB visual confirmation system with posting to require newly registered members and guests to enter a code before their post is entered in your database. Posts from new members can also be blocked if the message contains the contents of their website profile field.
To avoid inconveniencing your legitimate members, you can set the number of posts for which new members must enter visual confirmation.
Several alternate forms of visual confirmation are supported, including Advanced Visual Confirmation
, Photo Visual Confirmation
and FreeCap Visual Confirmation. These must be installed separately for this hack to support them.
