Blocklist(2,3) only works on certain action='s

If you create custom actions and want the Blocklist to activate,  
there may be some custom coding involved.  Blocklist only checks the  
IP address of the person who submits edit (& commentbox?) and the  
text submitted via $_POST['text'].

Which reminds me that I have to change a form to only be submitted by  
someone with certain permissions.  Any clue how to do that? :)
