there is also the banned_links property of the ZWiki folder, which can
contain regexes that are banned. Are you using this Bill? Mine
currently contains:
<\s*div\s+style\s*=\s*['"]\s*display\s*:\s*none\s*;?['"]>

A more sophisticated, long-term solution is to add code to ZWiki to
check against SURBL: http://www.surbl.org/ (Spam URI Realtime
Blocklists)

might have to stop using the word if it were tied down to any one
meaning." -- George Orwell
