It was originally a 180-day suspension in a humongous banwave for everyone replacing or injecting game files, including cosmetic model swappers. Blizz backed down on banning users of the less abusive use cases (cosmetic, rather than those who hacked models for practical in-game advantage). But I’m willing to bet that the warning is the only one that wil be given to the community. I would expect some kind of suspension action from now on.
