i will post you the answer from the du4 board:
hi
i don't know if this is an appeal or not.
you are only being banned for 120 minutes because you started esp/wallhacking only in the last few minutes.
if time is over, feel free to join any du4 server and play, but if you are caught hacking one more time you will be banned permanently from all du4 servers.
greets weavii
after opening 4 threads and several warnings you got banned from the forums for 24 hours aswell.
in case you really didn't understand my answer (which i doubt), here is a tl;dr:
player can see through walls -> player gets banned for
only 2 hours -> second chance to prove he/she can play fair
