This looks like ordinary wikispam. If you have an open-for-editing wiki,  
this can happen sometimes. The spam is posted by automated bots, not by  
humans. If you set a password, even if it is displayed in your wiki pages or  
on the login form, the spam will stop. See:
   http://www.pmwiki.org/wiki/Cookbook/OpenPass-Talk for something I use.

On pmwiki.org we have some spam filters which block most of the spam, see:

When you enable the passwords/protections, you need to clean the spam from  
your pages. For the documentation like PmWikiDe.PmWikiDe, in general you  
have a clean version in wikilib.d, so you just delete the file from wiki.d  
and the original one will appear automatically.
