DO NOT USE THIS PLUGIN WITH FUN MODS (SuperHero, Zombie, War3FT and so on)

The code is not optimized because i'm just good gamer and not the programmer but it works great. The main idea is that it bans the cheater after 2 rounds of cheating. It is made in compatibility with ATAC and slap commands that make fast teleports and may be suggested as speedhack cheat.

This plugin may be usefull on CSDM because it is difficult to check players while admin is out or always alive.

This plugin is switched off on fy_ maps, kz_, surf_, on aim_aztec, aim_sk_awp and awp_teamwave (because of start teleports)

It works on these one:
(FAST MAPS)
aim_map
aim_ak-colt
aim_headshot
awp_india
awp_map2
de_dust_arena
cs_pf_dust
cs_cock
AND
(CLASSIC MAPS)

de_inferno
de_dust2
de_aztec
