Next, the term "hack client" is common in gaming. Hack clients are modified versions of game clients that provide unfair advantages like aimbots, wallhacks, etc. So the user is probably asking what kind of hack client Wemmbu uses. But if Wemmbu isn't a known game, this is tricky. Maybe the user is referring to a specific game they're playing and mistakenly mentioned Wemmbu. Alternatively, perhaps they're referring to a modded client for a popular game but named it Wemmbu.
