How to roll back a page to a previous version
Sometimes people spam wiki pages with links other sites because they want to boost their search engine placings. It's easy to roll the pages back to a previous version after such vandalism.
- Click on "view other revisions"
- Pick last unspammed revision and click link to view it.
- Select "edit revision XXX of this page"
- Click save.
The page will now be replaced with the previous revision. Please make sure that you do roll back to the last non-spammed page revision, rather than editing the text of the spammed page. It appears that some spammers are harvesting page content some weeks before spamming the wiki, as they replace the current revision of the page with an older revision containing spam links. If you simply manually remove the spam links rather than rolling back the page content, this then leaves incorrect or out-of-date content on the page.
