[2019] Bungie Help on Twitter: We’ve identified an issue where our AFK Detection was not working properly for Gambit and Gambit Prime. We have resolved the issue, and players will now be kicked to orbit, and possibly restricted, if they are idle for multiple matches.

Re: Does this detect (X, Y, Z)?

We've stated a few times today that we aren't going to get granular on the details.

If we give details or hints on how it works, what it works against, what it doesn't work against, or other details in general, we risk giving valuable info to those working to circumvent the system.

End of the day: If you want rewards, play the game. Don't AFK. Don't abuse Macros. Don't leave your team mates hanging.

Cheers!
