CheckUser evidence has determined that this IP address has been used abusively;the address has been blocked temporarily or permanently to prevent further abuse.
If you are a registered user and are seeing this message, please post  on your talk page, with a notereferencing this message. Please be sure to include the IP address (which should appear at the bottom of the block message). Administrators should not undo any block that is specifically called a "Checkuser" block. Period. The Checkuser knows something that you don't. If the unblock template goes up you need to ask the Checkuser why the block is there. The Checkuser might not tell you, but they will review the situation and decide whether the block can be lifted. It may not be obvious why that block is in place, but there is a reason.[2] (see: block log • current autoblocks)
