OpMe was originally a simple bukkit plugin for 1.4.x and killed players by tricking them to think /opme will op them.
It would be told by a user saying "Want to be op? Do /opme!" or something like that.
Since it was old and outdated, i updated it for 1.8 but some features are missing.
What the command does on executing:
Clears the player's inventory,
Kills the player with 21 damage,
Kicks the player.
