I have deleted the spam. In fact I have regularly deleted about 3 or 4 examples of this kind of spam on the Axiom Wiki almost everyday over the last month or so. This spam is not coming via email. Believe it or not some abuser actually goes to the trouble of posting such messages to random pages. The point, I think, is to increase the "link counts" to the target pages by "seeding" links to the pages from where ever wiki software allows them to add links. This makes it much more likely that the search engines like google will index their pages. I regularly use "recent changes" to check for this stuff and delete it using the Zope undo feature (if possible, sometimes it is not if there has been an later update to the wiki), or by copying an earlier un-spammed version of the page to current. > Can there something be done (apart from manually removing it)? > One thing that would slow them down at least would be to require users to identify themselves via 'preferences' before being allowed to post a comment. > Bill, is there a way to include a spamchecker? > I will look into this some more, but it is difficult on the web. The Zwiki developers have been struggling with this for some time.
