Blocking is rarely used in "defense" of RationalWiki.
Some Almost every sysop issue "joke blocks" on their fellow sysops, lasting a few seconds to a couple minutes in length (although overuse of two-minute-plus blocks, or blocks against sysops in the middle of editing, are not always appreciated by the blockee).
Also, users may request that their IP address be blocked to force them to log in, or simply block it themselves.
Sysops should exercise caution when issuing blocks. The "vandal bin", which reduces the edit rate of people consigned to it, avoids the problems of blocking (
specifically, that if the blockee is not a sysop, they have no way of protesting it blocked users can still edit their talk pages), and it is especially important to avoid mistakenly blocking innocent non-vandal editors, particularly if they're newcomers.
