Current anti-spam measures
- External links in this wiki have the rel=nofollow attribute, which means Google will ignore them and a spammer will get no Google ranking boost from the wiki at all. Therefore, spamming is pointless. However, since spammers either do not read this information or do not understand or believe it, several other measures have been taken:
- IP filtering: users identified by IP adresses corresponding to known open proxies are not allowed to make edits
- Spam text filtering: edits containing typical spam words (viagra etc.) or spam site links are rejected automatically
- Robot filtering: Recaptcha is triggered for edits and account creation by non-identified users
