So obviously changing cdkeys does nothing now
but does running multiple cdkeys at once for example 3 characters
go off the same 20 games/per hour cooldown or are they each individual

It’s not the start that’s the problem, it’s leaving the game at the same time that got you. Stagger quit times and that won’t happen again. You also just need a new ip address to get back on so if your phone has a hot spot that’s all you need to get back in.
