Activision cracking down on popular Call of Duty: Warzone app that basically constituted cheating

"Lobby shopping" is what Call of Duty: Warzone players have been calling the ability to check the skill level of players in a lobby prior to joining it, enabling them to pass on those that include a lot of tough competition. There are several ways players, notably Twitch streamers and content creators, have been able to do that over the years. But the use of one app in particular - Warzone Agent - has been considered by many to be cheating, and Activision is finally doing something about it.
