How to detect xray without plugin on a Gregtech5 server

  • Hello


    I'm looking for something to detect players who use Xray on my server.

    My server runs on version 1.4.7 and ore generation is from Gregtech5 mod.

    I don't want to add plugins on my server cause it's a private modpack with more than 100mods i want to keep stability.

    I can't detect players who use xray by seeing who mine lot of ores in a short time cause of gt5 generation.


    Somebody know one issue to this problem?


    Sry for my bad english, i'm french.
