Note: if a user "steals" artwork from others, there is nothing you can do to "force" them not to do so unless you are the copyright owner of the original work. What you can do is:
 * 1) Politely ask the user not to use artwork for which they do not own the copyright
 * 2) Bring the matter to the attention of the local admin(s)
 * 3) Use Special:Contact to ask Wikia staff for advice

If you are in fact the copyright owner of a work that someone else is using without your permission, and you have tried all of the above, the last option you have is to send a DMCA takedown notice to Wikia's designated copyright agent in accordance with Terms_of_Use

Note: you may wish to read DMCA_Takedown_Notice for more details. A DMCA takedown notice is an official form that you must fill out.
