Vandalism is an unfortunate side-effect of maintaining a database on the internet which anyone can edit. It can appear in many forms: Testing, Obscenities, Link-Spamming and/or Advertising. While some forms are considered more malicious than others, all are a nuissance and must be cleaned up... Testing vandalism is often not malicious at all. It is usually a result of a brand new user 'trying' out our database; seeing if they can actually make live changes. These edits still need to be tidied up, but usually can be done knowing that it won't happen again.
