Just looked at their website and it says the following: "Due to legal complications Lazybot is currently not accessible" Looks like Blizz is really trying to get rid of all the bots. Nobody wants to fight against Blizz except for HB it looks like.
I could imagine that if HB won the legal fight, Blizzard would go crazy and unleash many banwaves on the bot. Mostly because they would be embarrassed for there loss or something haha.
I do not think it is a matter of "guts". We are talking about business here. Maybe this bot has a better chance to defend than the others. If such a large company is suing you have every right to be scared.
