/*
	easyblock.js - Script to quickly block spambots
	By Legoktm, with assistance from Ori.livneh and MZMcBride

	Adds two tabs, "OP: Spambot block" and "Spambot block".
	OP will block for 6 months, and regular will do 3.
	If the user is an account, it will be indefinite.
	The script will forward you to Special:Nuke once done.

	This script very likely may contain bugs, use at your
	own risk.

	Released under the MIT License, see README.txt for details.
