|This page in a nutshell: Vandals are people who deliberately attempt to damage Wikipedia, not those who make adverse edits.|
One problem newcomers and inexperienced editors have on Wikipedia, is using popular terms in a wider variety of circumstances than is appropriate. One such word is "vandal".
According to Wikipedia:Vandalism, vandalism is "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." This definition is excessively broad, even for the purposes of broad policy coverage. It goes on to restrict what constitutes "vandalism", however, saying emphatically that "[e]ven if misguided, willfully against consensus, or disruptive, any good-faith effort to improve the encyclopedia is not vandalism."
Note that the definition does not mention:
As a result, the word "vandal" should not be used in reference to any contributor in good standing or to any edits that can arguably be construed as good-faithed.
Non-vandalism disruption may also occur. Instead of calling a person committing such disruption a "vandal", you are better off discussing his or her specific edits with him or her. Comment on the content and substance of his or her edits or arguments, not his or her person.
