The Mii Ghosts were 6 users and they were famous for yeahing the same posts several times. In the beginning, their goal was thought to be frightening naive users all around Miiverse, but it was later revealed that their goal was to "stop bullying and spread positivity". According to the more loquacious Mii Ghost, they had to gain users' attention by posing as 'ghosts', then use the attention to spread the word of positivity. When the Mii Ghosts first came about, the 6th of the group went as far as to reference the number '666' in a post, in order to 'gain attention'.
TotallyMiiGhost (the most active of the group) began losing popularity in August 2014. She then went on a 5 month hiatus from September 2014 to March 2015. When she returned, her popularity had decreased dramatically. Her quoting posts which usually got anywhere from 100 to 300 yeahs now only get around 10 to 20 yeahs. Mii Ghost still visits Miiverse occasionally to post about whatever.
