BGMI was banned by the Indian government over its privacy and user data concerns. There was also an issue where BGMI was said to be linked with China, making it eligible for a ban order that was similar to what was seen with PUBG Mobile.

The game is not officially stated as being banned but the developers are barred from openly distributing the game, basically making it impossible for Krafton to provide the game to new users or give any update to existing users.

Ghatak is known to be vocal about BGMI and its several other aspects and ban is currently the major aspect out of it. He did not mention about any unban date on his Livestream or any other platforms but has said that BGMI will return for sure.

The creators are sensibly answering this and Ghatak being one of the oldest from the community has stated that BGMI ban will be lifted but the time duration is not available yet.
