This morning I found three spam entries in my wiki. Looked suspiciously like previous encoded entries except they had the following at the top of the page.

NOTICE: The data below is posted by a program which is part of the Graffiti research project from Brown University. We will remove the data from your site once the experiment is finished. If you want to delete this, please do so as you would delete a spam page. For more information, please visit http://graffiti.cs.brown.edu/info/.

What I want to ok now is how can block encrypted data from being posted.. I came up with a filter that appeared to beable to block the previous posts like this.

Also is there a standard way to limit the size of any given page as these blocks of encoded text are fairly large (87510 bytes/characters).

Thanks

It looks like it won't post on sites that require a CAPTCHA for registration (and presumably it won't get far if they require one for editing); take a look at http://www.mediawiki.org/wiki/Extension:ConfirmEdithttp://www.mediawiki.org/wiki/Extension:ConfirmEdit .

You could also contact the administration at Brown or their computer science department and tell them that maybe this isn't the sort of thing their institution wants to be associated with. On the other hand, speculation about this sort of activity isn't new < http://thread.gmane.org/gmane.org.wikimedia.mediawiki/24459%3E, and other people working on it for more nefarious ends aren't going to be so transparent.
