There’s undoubtedly some automation to capture people deemed worth investigating, but consider the fact that a single person can probably investigate possibly 5-10 flagged cases a minute. Times that by 3-5 people investigating and that’s 15-50 cases per minute. 400 people across an entire day is nowhere near hard to accomplish. Those who were banned before logging in could likely have been banned before in the beta or triggered an actual automated ban targeting specifically malicious software (whether the persons knew they had it installed or not). Some cheat software used on other games, even if not launched, we’ve known since the beta would cause bans. And also, Bungie I believe said some game and computer failures are not actually bans. So no, I remain skeptical it’s thousands and if it is, I’m still skeptical it adds up to somehow a majority being wrongfully done or some malicious conspiracy.
