It’s important to understand that there’s a distinction between blocking and banning in Wikipedia. Banning usually occurs by community consensus or Arbitration Committee decision. If you were banned in this manner, understand that your appeal will likely not even be considered unless it’s been a long period of time after your ban initially started. Typically, for an un-ban request to have any sort of chance to succeed, you must wait at least six months before submitting a request. Do not forget to cheer yourself up if you are innocent. If you did nothing wrong on Wikipedia and you are blocked, you should know that it is not your fault. In fact, cheer up with something else that you like and wait for that ugly template to go away.

Show that you understand why you were blocked and your understanding of the policy you were against. Address the reason for your block in your reasoning. Admit that you did something wrong and that it won’t happen again. Show that the block is not necessary to stop you from causing further problems on the site. Give links as evidence.

If you do get unblocked, then be sure not to repeat the behavior that got you blocked in the past. To prevent this, editing restrictions may be set to alert you that this is your final chance, and that any further misbehavior may result in a block for good.
