3. The Miiverse War [mid 2013 to early 2014] The worst thing to happen to Miiverse, at least in my POV. The Miiverse users were furious with the Admins for banning them for no reason, so they revolted (idiotically). They said harmful things and got themselves banned, and in the end, thousands were permabanned and some were tempabanned, and the Badmins still ban people to this day but isn't as bad.
