If we talk about percentages, this method would only cover 20% effectiveness, and I am being generous.

This has nothing to do with Adrenaline Gamer (the legitimate Half-Life mod, which has its' own servers), this is about an unauthorized illegitimate Half-Life cheat client which can be used to play in normal Half-Life servers.
I am intentionally vague about the details because this forum has strict rules against advocating cheating (and rightfully so), so I obviously can't point towards this cheat client explicitly.
Remember, the idea is about blocking cheats, not spreading them

If you know about some other versions in the wild which have other CVARs than ones posted, please contribute so this can be improved !

One idea could be to try detecting perfect bunnyhopping and ducktapping server-side, that if a player executes bhop/ducktap perfectly 100% of the time it's definitely a cheater. This would also block other cheats than the mentioned "BHL". But this would require some CPU usage and also be harder to make. I think that long ago anti-cheat plugins for SourceMod zBlock and/or SMAC had this functionality but I'm not 100% sure about this as they are defunct nowadays and it's been quite a long while.

The fight against cheaters has obviously always been an uphill battle, and we can only do what we can.
Meanwhile the good thing about this plugin is that it uses basically zero CPU and it's an easy way to get rid of at least some of them.
