On the 11th of November, the Discord server of GTA 6 Mapping Project disappeared. It was a key place for people to share leaked location data. It's speculated within the community that it may have been taken down after a DMCA takedown from Take-Two Interactive on the server to have it removed from Discord.
Publisher targets community leak hub as fans lose primary map data source
With it now gone, that's one of the biggest sources for people to be examining the world of the game before it's released. This just goes to show how controlling the publisher is with information leading up to the release.
Take-Two Interactive is the publisher of the game that's being released. What we're seeing them do is start targeting these community projects that are sharing unconfirmed leaks and map data. The GTA 6 Mapping Project was a shared place for people to come together and get their eyes on visuals from footage to merge it together. The fact that it's now gone tells us that the publisher has changed its approach on how they're handling fan-made content before it's released.
Even though the Discord server has gone, the website, State of Leonida, is still available for map data. This gives a lot of geographical data on what's being shown in available game footage. Towards the end of October, it was announced via GTA Wiki that they'd co-own it to make sure this resource would stay available after the game's released. Likely, the content for it was shifted to more stable hosting to avoid this sort of thing.
It's believed that this legal action taken is due to a DMCA request rather than something internal to the project. However, it's unknown as to what specifically caused this to be shut down, per the source. This is unclear which leaves everyone in the community wondering what sort of enforcement Take-Two is trying to do here. This is a warning for other fan projects that are sharing leaked assets.
The shutdown of this Discord server is an important change in how Take-Two is dealing with things before it releases. There'll likely be more pressure on GTA 6's community resources. You'll have to make do with just the archived data or another form of hosting to analyze the map. It shows that they mean business when it comes to what's shared before it's released.

Take-Two is erasing history. The State of Leonida site is the only archive left now.
