Posting guild advertisements on pages other than on the Share:Guild page.
Repetitive words or lines typed out by a user using the comment section under the articles.
Adding external links to an article or user page for the purpose of promoting a website or a product.
If you see a spam or any general vandalism, link it here; post it under the reply section. An admin will remove or fix that spam as soon as possible.
If you see your post deleted, it means the spam is removed/fixed.
If you see a very heavy spam (i.e., editors started deleting 5 pages), and see no active Admin at the moment, report the vandalism to the Volunteer Spam Task Forces (VSTF’s) here: http://vstf.wikia.com/wiki/VSTF_Wiki
Note: If you are unsure about anything, please feel free to post it here. An admin will either address the specific issue or let you know why it is not a concern.
