##If the user should be blocked based on his actions on the wiki, carefully consider how long  the user should be blocked. If the user is a blatant vandal, generally 6 month blocks are handed out. If the user is merely edit warring or some similar offense, a shorter block (2 days, a few weeks, months?) is more appropriate after warnings are given out. Keep in mind that users and IP addresses can change - long term and infinite blocks are therefore discouraged.

#If you have run checkuser (which you should generally only do with probable cause) and determined the user has created sock-puppet accounts, the user should be blocked. Be wary that multiple distinct users might just be editing from a public location - for example a school, a coffee house or a library.

#Furthermore, users with blocking rights must be very careful in the issuance of a block. Unwarranted blocks that may be undone clog the block log, and future Administrators may unfairly consider an established user as a troublemaker, when the real problem lies with an unjustifiable block made by an Administrator. When a blocking error occurs, it's best for everyone involved for the original blocking editor to undo the action so as to limit confusion. However, this is not always possible.
