He's trying to figure out what causes it, that's why he's said to use the no memory writing shortcut to start the bot.
Plus if he publically says whenever he is looking into something, they can just turn off their anti-cheat for a while or decide to ban in waves to make it so much harder to protect against detection.
Not only that, but CLEARLY Namreeb or Tauri has come up with another Warden module (btw, last time Warmane had a detection, they bought it from Tauri) that does something the previous modules could not. It's not about "being terrible", it's about knowledge that wasn't available previously. In fact, I've heard rumors about a vanilla client warden exploit that lets you execute any code you want on the system the WoW client is on. Both NW and LH implemented this around the same time. Hence why it's very likely someone (like Namreeb) came up with it and published it to server owners (as he usually does).
The last Tauri detection took him a while to fix too, because they made it extra hard on him to find what they were doing different. So give it some time and don't spam or you're lowering your chances.
