I think he's asking if it is possible (and which user rights would be necessary) to enable the extension which allows abuse filters to retroactively block multiple IP addresses used by a blocked user, rather than just the most recent one. If he is, then this thread might be relevant; if I'm reading it correctly, it appears that support for angry-autoblock has been removed from MediaWiki.
