Help:Wiki Spam

Wiki Spam is the unwanted insertion of advertisements with external links in the wiki. The purpose of this vandalism is to promote external websites in search engines such as Google.

Spammers note: external links in this wiki have the rel=nofollow attribute, which means Google will ignore them and you will get no Google ranking boost from the wiki at all. Therefore, spamming is pointless.

Monitoring unwanted edits

Use "Recent changes" to monitor unwanted edits.

Reverting unwanted edits

Legitimate users: you can help undoing unwanted edits.

• Add a summary, such as "revert spam" and click the 'Save' button.

Current anti-spam measures

• 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
