We really need to wait for details/numbers before assuming things like Discord/OBS aren’t on a list in the anti-cheat software (so their attempts to inject into the program are disabled but doesn’t ban the account doing so - a silent failure of the intent of injecting because it is deemed not malicious, which is what appeared to happen in the beta).
If GeForce Experience is a bannable offence then we can wait for the numbers. The majority of gaming systems are nVidia and that software is the default way of getting drivers (needed to play Destiny 2) from the manufacturer and promotes the instant-rewind capture feature and overlay info heavily (as well as consoles normalising that as a feature of modern gaming systems). We’re going to see, even for a ban that only triggers on a specific version of GFE, hundreds of thousands of bans for such an incorrect ban. Possibly millions if D2 sells well on PC and it affects the current version of GFE. You can see my scepticism about that potentially being the case.
If OBS or Discord overlays are generating bans rather than being silently suppressed as “known behaviour, not supported” then we will also see very significant number of people affected. We’ll see “look, just load it up and five minutes later, ban” videos reporting to show that this is something you can try and how, because we know exactly why these bans are happening and Bungie need to fix it and work out who they banned in error. What we are claiming here is that everyone using Discord (with overlays enabled) or OBS while playing Destiny 2 will be banned in the next few days. If that is what is happening then we are expecting that to happen.
My bet is that we won’t because this has been tested, there is a whitelist for both allowing overlays and silently blocking them without repercussions because they’re not malicious. What we are seeing is a few false positives (as no system is perfect and Destiny 2 is a big game launch so lots of players) and a lot of people who had Discord or OBS up but also had CheatEngine or some DirectX dll injection active which the anti-cheat detected and used as grounds for a ban. Even if those things weren’t being used to cheat in PvP and just happened to be active and scanning/injecting due to a misconfiguration. Because every other time people get banned from online moderated play that turns out to be why almost all of them were banned.
