Global blocking (sometimes shortened to globalling) is a feature and wiki concept used by wiki farms such as Wikia, Wikimedia Foundation, ShoutWiki, and Brickimedia to prevent global vandals, spammers, or other undesirables from editing their wiki site(s).
Accessed through the phalanx function, global blocking is often confused with account disabling, when in fact they are different; global blocking is often forced upon, while account disabling is usually deliberate. However, if a user is globally blocked forever, staff will generally disable the account as well, removing its avatar and profile information.
Global blocking also happens on Wikia if a user is underage, or for major sockpuppetry.
