Re: incredibly cheats
it was/is real!!!!
around 2 years ago, when i first came in contact with mods
there was an modpack where this was in it (do not know name of it) it is a “transmitter” that sends info if players did had that mod.
it worked only if the enemy and you did have the “transmitter”
you can see all the info on the minimap and the enemy (who is using the same mod) will also see all positions on the minimap)
i am not totally sure about all the info and i thought this “transmitter” was banned pretty quick
