IMPORTANT
Because there has been an increase in people removing {{Cleanup}}, it seems that I must remind you all that the removal of the Cleanup Template WILL result in the deletion of the page* and/or the immediate banning of the violating User that will last 3+ months. Consider this your final warning.
DO NOT REMOVE THE CLEANUP TEMPLATE!!!


P.S.
Addition of {{Checks Out}} to pages by unauthorized Users is an attempt to bypass Admin Review, and will result in a ban lasting 1 year or more. This is your only warning.
