I do think hardware ban will cause them to lose money to because most of these "legit" people you guys think are so **** pro are actually hackers just playing it off good. I know you'll say "oh he doesn't hack" or "are you dumb rofl lmao he is runner up in nats" or some dumb thing like that but in the end, do you sit next to him and watch him play? Naw you don't. Anyways those people are big money spenders (hackers). Why? Becuase if they can buy a hack for a free game then they will certainly spend money to play the game.
Anyways it is a valid point but I doubt bad enough to significantly make a dent in their pockets.
Hardware ban is easy to bypass but most people don't know how to do it. IP ban is just dumb, I could change my IP in 7th grade and I'm now in my 2rd year of college.
Edit: Yea that update was dumb, it lasted at the tops 20 minutes for me until I saw a hacker. I figured it wouldn't last long anyways.
