[edit] Issues with sv_cheats

Like any source based games, sv_cheats may be fun to enable for your players. If you do enable sv_cheats please note that your server will stop responding to server queries from the outside. This may break any type of monitoring scripts you may have running on your server. This will also keep the server from showing up in steam community server queries as well as lobby system players.

Only use sv_cheats if you understand the implications that may come with the cvar enabled.
