Advanced banning: Set your own banning rules for different hack attack codes. Even create your own ban pages (e.g. to mimic law enforcement bans for spammers).

Code overrides: Implement modifications to the Composr code without directly editing the original code by creating _custom files. This makes upgrading much easier. Also supports contentious_overrides hooks and the override_api for more advanced overriding.

(Conversr Only)

Issue warnings (with an optional Private Topic sent to them) for unruly members. Optionally include one or more of several punitive actions as explained below.

Ban the member's IP address so they can no longer access the site from that device (this also adds their IP address in your htaccess file)

Ban the member so they can no longer log in (and their profile can no longer be viewed by others except high-ranking staff)

Report spammers to public blocklists such as Stop Forum Spam

Put members in a special restricted 'probation' usergroup for a specified number of days

Silence a member from the forum or topic on which they made their problematic post (this also works on comments).

Charge points from the member's balance (also affects rank points to penalise their ability to rank up)
