The way to get this reviewed is through an appeal.
Just a reminder. Multiboxing is allowed - it is not supported.
Botting is strictly verboten.
Very different things, but that also doesn’t mean a multiboxer couldn’t also be botting - or using shortcuts that count as botting. Most don’t put that kind of investment at risk - but some do.
Never use anything that can produce actions with one key press that can’t also be done through the in-game systems. Be it software or hardware. Just because say a mouse CAN do something, doesn’t mean you should.
I’ve not looked into this, a GM will need to do that - but if a multiboxer truly runs afoul of the rules, that is often what has happened. This is more of a FYI.
Open an appeal and have this reviewed. False positives are rare, but they of course can happen. That is why we have an appeals process
