In game 1931 leaves and leaf were both counted. This is a bug and if the habitual players knew this and used it (15 and 11 votes) it is sadly bug-abuse.

i demand a banning. no tolerance for bug abusers

Bans can be circumvented. Only dozens of papercuts on their fingertips will put a stop to this.

Don't be evil-minded. “Leaves” is the third-person singular form of leave.
