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*;?['"]>
(?:\.ec\d+|58798309dyb|bzyc|yunching|fadaka|fixtab|hobbyworkshop|port5|topsitesranking|shigao|quiw|isavecoupons|free-poker.*|g4h5|freeonlineslots.*|poker-game.*|mrstab|onlinecasino.*|glwb|zerohops|areaseo|rwr|insulate|itascacc|gayhomes)\.(?:com|net|org|cn|org\.uk|info|ru)
(?:mujweb\.cz|buy-soma-online\.biz\.st)
(?:albenza|elimite|eurax|vermox|tamiflu|amoxicillin|tetracycline|zithromax|buspar|colchicine|zyloprim|alesse|mircette|triphasil|yasmin|aldactone|norvasc|darvocet|diazepam|didrex|diethylpropion|diflucan|effexor|clonazepam|cyclobenzaprine|fluoxetine|fosamax|fioricet|flexeril|lexapro|lipitor|hydrocodone|levitra|viagra|cialis)

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

    "It is almost universally felt that when we call a country
    democratic we are praising it; consequently, the defenders of every
    kind of regime claim that it is a democracy, and fear that they
    might have to stop using the word if it were tied down to any one
    meaning." -- George Orwell
