Bats

Bats are these rotten creatures taken straight from hell to collect souls  made into mappers, they're known trolls in google +, and have been involved in dramas since 2017. Bats are obsessed with emoji.

History
The first bat was ultraman mapping fiction & history , followed by  dutch bat mapping and so on. Tons of new bats appeared later, and this concluded with the creation of the bat mapping community. Communities like the Mapper Marine Corps and TMC have tried to stop them, failing misserably at erradicating the pest.

Bats as weapons
Bats, despite being annoying, have been supported by normal communities, but, why would a community support this concentration of trolls?. Easy, bats are usefull to raid communities you don't like or using them as excuse to attack communities that are against bats. Even communities that used to ban bats ended up collaborating with them, and that's why bats existed as long as they did.

Demise
Nobody stopped bats, but with the time, the bats themeselves lost interest and lost members and relevance gradually, but all mappers will remember their legacy.
