If you are a site admin and want to give your moderators the power to block spammers, then this plugin may be of interest to you.

It allows mods to change the forum role for a user to blocked which will stop them from using the forum.
It does not allow mods to change a user’s WP role.
It does not give mods additional access to wp-admin.

You can get it from the WP repo:
bbp Auto Block Spammers

Or from PhiloPress.
