Vandalism
Vandalism is a crime that is done by destroying or damaging the property of someone else. This can include graffiti and website damage.
A person that does this is called a vandal. The name comes from the Vandals, a tribe that attacked and damaged the city of Rome in 455 CE.
Examples
Examples of physical vandalism include salting lawns, cutting trees without permission, egg throwing, breaking windows, arson, spraying paint on others' properties, and tagging.

Many websites, such as wikis (like Wikipedia), forums, and blogs, can be changed by anyone. Because of this, they can be "vandalised" by adding comments or replacing everything on the page with spam, nonsense or other silly content. It is a kind of trolling, and these websites have special users, called administrators, whose job is to remove the vandalism and to block users who do not stop vandalising.
