Yesterday we randomly got hit by spam bots on our wiki, we have reverted all the damage done to main and user pages so nothing should be left. To make sure that doesn't happen again I have blocked certain HTML expressions on the wiki. They shouldn't really stop you editing as they're ones that are never used on a wiki but widely used by bots. If you do have any issues and get blocked make a ticket and paste the error you got.

Also as an added precaution we have removed every staff email from pages and removed some user email. If you have saved an email onto your page we highly suggest you remove it. Otherwise you run the risk of getting it copied by a crawler then being spammed until the bot dies/email is removed from the list.
