If a wiki page has been hit by a spambot you can revert changes by:
- Select the page's 'history' tab
- Click on the date/time link for the most recent version of the page before it got spammed
- Select 'edit', it'll warn you that you're editing an old version of the page
- Select 'save'
If a page has had legitimate changes since it got spammed then the spam has to be picked out more carefully.
List any spambot users here and I'll block them:
