lemmy.world/c/minecraft is growing steadily and we are currently negotiating with mods from the subreddit to get them onboard if they desire to learn and migrate to Lemmy. One already joined our moderation team.
I don't expect official accounts to come here anytime soon, we simply do not have the reach or public awareness necessary to make it a viable channel. However, we are slowly building the rapport and structure necessary to accommodate CS representatives, developers and similar persons in the future.
