how do you know if someone is using xray

Its obvious. I.e. They dig straight down one block and bam diamonds

use it = SUPERBAN

i always know when someone uses it

i know 69% of the time <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f609.svg?0" type="image/svg+xml" standby=";)">;)</object>

I hate people who use it.

Just ruins the point of survivul.

What survival? Minetowns survival? O.O

i hate people who use xray, especially when they use it to destroy hidden ww bases

i have made a private server for me and my buddies and im suspicious is there any like command or mod way to be sertant hes using xray or is it all just suspicion . are there any ways to be positive

no way to be 100% unless you use his JAR
