To improve player safety, we are also going to deprecate player identifiers from being publicly accessible on servers’ players.json endpoint as well as from our server list backend in the coming weeks.
Server owners who want to retain identifiers on their players.json for backward-compatibility will be able to use the sv_exposePlayerIdentifiersInHttpEndpoint ConVar, but we will implement a safer alternative later this year, allowing for a security string to be passed when querying players.json.
