Vandalism

Vandalism is the act of irritating and angering people on wikis through the use of destruction, construction, and social engineering. Popularized on Wikia by teams, vandalism has become a serious problem for admins and can bring drama into wikis.

Trolling, however, is different from vandalism, because afterwards vandals give their items back, and repair any damage they did.

How to prevent vandalism on your wiki
While there is not much that can stop a determined vandal, there are ways for a wiki to reduce the risks of being vandalized. The following is a list of steps wiki owners can take to try to keep their wiki protected:
 * Protect the major/important pages on your wiki so only registered users and your staff can edit them.
 * Do not let your staff abuse their rights. Also, be cautious when choosing admin/bureaucrat rights for your staff. Once you promote a user to bureaucrat, the promotion will be permanent and only Wikia staff or the user themself can remove it.
 * If abuse happens in severe cases, it may be a good idea to be an only bureaucrat and admin.
 * Be careful what rights your staff wants to have.
 * Be aware where you advertise the wiki. While exposure means more members, vandals can find it easily.
 * Become familiar with what vandals are capable of doing. There are no hacks to gain admin/bureaucrat rights or delete the wiki.
 * You must ban users who vandalize the wiki. Depending on your wiki's rules, bans can be assigned for initial or repeated vandalism.
