So in all of the networks ive realised some hackers like to fly under/ all the way on top of the map so nobody can find them. Why not program a "cheat detector" where if it detects for example someone is 30 blocks under the top of an isalnd, they get banned for hacking, because there is almost no way to get there besides than hackers. For the problem with hackers on top, justhave a height limit and if anyone is above the heightlimit, theyll be banned as a legit player can only stack up to the height limit while hackers can just fly into the sky.
