Wiki spam has become very common and the spammers are using more and more advanced techniques. It is now common that spammers use automated bots to edit many pages automatically. They also often have access to many different proxies and IP addresses. This makes it increasingly difficult to fight spam. Due to the advanced spam techniques used by the spammers spam control often needs to be done by an administrator.
Here is a small check-list on what administrators should do when they find spam in the Wiki:
1. Block the offending user
- This is most easily done by clicking the "block" link in the recent changes list. Use an infinite expiry time. Blocking of a specific user, IP address or IP address range can also be done on the block page page. If a bot was used to register many users you can identify and block them all quickly by using the user creation log (in Firefox you can hold down control while you click each "block" in order to blcok in parallel on different tabs).
