www.wikicrozma.com:VANDAL
(Ported.)
On this site, vandalism has a very specific meaning: editing (or other behavior) deliberately intended to obstruct or defeat the project's purpose, which is to create a free encyclopedia, in a variety of languages, presenting the sum of all human knowledge.
The malicious removal of content, or the changing of such content beyond all recognition, without any regard to our core content policies of neutral point of view (which does not mean no point of view), verifiability and no original research, is a deliberate attempt to damage the site. There, of course, exist more juvenile forms of vandalism, such as adding irrelevant obscenities or crude humor to a page, illegitimately blanking pages, and inserting obvious nonsense into a page. Abusive creation or usage of user accounts and IP addresses may also constitute vandalism.
Vandalism is prohibited. While editors are encouraged to warn and educate vandals, warnings are by no means necessary for an administrator to block (although administrators usually only block when multiple warnings have been issued).
Even if misguided, willfully against consensus, or disruptive, any good-faith effort to improve the site is not vandalism.
