How to Block wikiSpam on wikiHow

Like the majority of Wiki sites, wikiHow receives numerous spam postings, some of which can be quite obscene. In order to prevent spam postings from being published we have enabled the SpamBlacklist Extension for preventing links that are known to be spam links from being posted on wikiHow. If you are a wikiHow administrator and have seen a spam posting, you can help prevent future postings by doing the following.

  • If you're having trouble determining whether an external link constitutes spam, consult the wikiHow Writer's Guide, which states:
  • wikiHow exists to help people, not for product promotion. While we encourage useful articles about how to shop and buy things, writers should refrain from creating articles to purely promote one specific business without providing useful insights to our readers. While you are welcome to post an external hyperlink, the WikiHow community reserves the right to delete hyperlinks or entire articles that over step the bounds on self-advertising.

  • A good way to tell if an external link was posted by a spammer is to visit the link and see if it provides valuable content. If all it does is overtly promote the purchase of a product or service, it's probably spam.
  • Admins can also add good websites which might accidentally be labeled as spam to the spam whitelist.
