Wikipedia:APPEAL

If your account was blocked by mistake, it will be reactivated very quickly, as soon as you let an administrator know of the problem. Otherwise, there is a rapid appeal process which obtains quick review by other independent administrators, and brief discussion of the matter. One aim of blocking in some cases, is to ensure the user learns from the incident, and that the issues don't happen again.

You may have breached a behavior rule without knowing it. The block notice contains the reason why an administrator has blocked you from editing, usually as a link to a policy or guideline; read it carefully and try to understand how your behavior did not follow it. A block is not intended as punishment; it's meant to prevent you from making disruptive edits, either in good faith or as vandalism. If you can show that you won't make those again, the block should be lifted.

If you don't understand some detail of the policy, you can ask the administrators that blocked you any clarification about their actions, and they're expected to answer them. Don't do such requests within the unblock request, though, as it should be used only when you already understand the reasons for the block.

If blocked you can usually appeal on , which is only blocked if abused. If you cannot edit your talk page then you must appeal via the Unblock Ticket Request System or by emailing the Arbitration Committee, see below.

Do you use an ISP or web accelerator that involves shared IPs? Common examples include Comcast, StarHub, schools, and colleges. If so, you may have been affected by collateral damage.

In such cases, you should request an account to be created for you so that you can edit despite the block, which only affects users who are not logged in.
