This code blocks the cheat client known as "BHL" which adds automatic perfect bunnyhopping and ducktapping to Half-Life. It is currently undetected by VAC.

With automatic perfect ducktap you can zoom up slopes and climb boxes faster than human ever could.
With automatic bunnyhop you can gain perfect speed in way is impossible for human.

And before you ask why so many cvars, it is because there are multiple versions of it out there with different cvars.

PHP Code:

#include <amxmodx>

#define AUTHOR "Anon"
#define PLUGIN "Block BHL"
#define VERSION "1.0"

public plugin_init() {
    register_plugin(PLUGIN, VERSION, AUTHOR)
}

public KickUser(id) {
  new address[32]
  get_user_ip(id, address, charsmax(address), 1)
  server_cmd("kick #%d;wait;addip 0 ^"%s^";wait;writeip", get_user_userid(id), address)
}

public BHLCheck(id, const cvar[], const szrValue[])
{
  if (!equal(szrValue,"Bad CVAR request")) {
    KickUser(id)
  }
}

public client_connect(id)
{
  if (!is_user_bot(id)) {
    query_client_cvar(id, "aghl_supports", "BHLCheck")
    query_client_cvar(id, "aghl_version", "BHLCheck")
    query_client_cvar(id, "hud_colortext", "BHLCheck")
    query_client_cvar(id, "hud_dim", "BHLCheck")
    query_client_cvar(id, "hud_strafeguide", "BHLCheck")
    query_client_cvar(id, "cl_messages_log", "BHLCheck")
    query_client_cvar(id, "cl_autojump", "BHLCheck")
    query_client_cvar(id, "cl_bunnyhop", "BHLCheck")
