People have been found from streams without minimaps probably 100 times. Most streamers of this game are covering their minimaps and still get found EVERY TIME.
Literally any player near water or near a biome that is regional will be instantly giving away their location. No programs are needed no "datamining" or anything special at all, landmarks and biomes are all that is needed. I have watched the discord chat pinpoint people from tiny cropped screenshots easily 100 times and have absolutely been able to do it myself within minutes.
Unless you are in the very center of a very common biome or underground you are 100% not safe from being found and it takes less effort to do this than it does to make a batch of lye.
That being said, do it.
Put the last nail in the coffin.
Make the game that much less enjoyable for the casuals who keep it alive during the last 8 months of the world.
