Going on a profile of someone with joins set to ‘Friends’ will show the game that the person is playing, even if you are not friends.
This allows anyone to manually join using the gameid exposed.
Note for people watching this: Join button will just say that user has left. It is only the presence API impacted. Join data is provided from this API, but it is not requested by the client.
This is what pops up when opening the page, I’m not sure if this is what’s supposed to show up, but I’m gonna assume that Roblox took action thankfully.
You need to do a “POST” type of request in order to use this link. Web browsers normally only use GET when you click on them normally. This seems to still happen and not fixed.
Update: The bad change has been rolled back. We are no longer able to reproduce the issue on our end. But please do let us know if you are still encountering this issue. Thanks!
