I decided to block any form of editing to the ossec wiki for reasons of vandalism. If you look at the wiki recent changes page you will see the changes that were made. Most of them were very strange to me, like removing every + (plus) from the pages or removing all the content (without adding any spam link or anything). Anyone seeing similar patterns?
After some log analysis I found that all the changes were made by the same IP address (126.96.36.199) across the last three days…

How do you guys handle vandalism/spam on your wikis? Any suggestion? Until I can find a solution to this, send me an e-mail if you need to edit the wiki.
