I Have Been Banned For No Reason

Hello Everybody

   I would just like to get this out here. i was playing like 2 hours ago on No Cancer Dark RP and was having a good time.
I made a group known as the rebellion and we were having fun raiding bases and pd. when i was raiding i killed a few people. next thing i know is that i'm banned for a couple of weeks. I was raiding not RDMing yet i got banned? I got no sit or warning whatsoever just straight out banned
