{{selfref|This page concerns the general phenomenon of vandalism on wikis; for information on vandalism to [[Wikipedia]], see [[Wikipedia:Vandalism]].}}

'''Wiki vandalism''' is generally defined as editing a [[wiki]] in a way that is intentionally disruptive or destructive. There are four generally acknowledged types of vandalism: deletion of legitimate information, insertion of nonsense or irrelevant content, addition of unwanted commercial links ([[link spam|spam]]), and policy violations specific to that wiki.

== Administrative response ==
Administrative responses vary from wiki to wiki, but most vandals are blocked by username or IP address when it becomes clear they are not simply experimenting. To mitigate spam, some wikis automatically add the "[[Spam in blogs#rel.3Dnofollow|rel=nofollow]]" attribute to all external links, which tells search engines to ignore those links and thereby largely negates any incentive to spam that wiki. Violations of policy are often severely dealt with by extended or indefinite blocks once it is clear that the user is not simply ignorant of the rules. Servers known as [[open proxy|open proxies]] allow users to circumvent blocks by changing their apparent address, and are often indefinitely blocked upon detection until they are closed...

Systems of wiki etiquette often exist to help prevent mistaken accusations of vandalism. However, such systems sometimes incite vandalism by giving administrators too many justifications for action, which may breed resentment among the wiki's members.

(contracted; show full) vandalism. Small wikis rarely have unmanageable vandalism problems, since they are protected by their relative obscurity. Even very politically charged ones such as [[openpolitics.ca]], [[dkosopedia]], or [[sourcewatch]] usually receive only a few attempts at vandalism from those opposed to their ideology. In general, [[spambot]]s are the most common vandals on small wikis.
