Duluxe bass

Hi guys, about 10 minutes ago I was playing on gsgamings main dayz server when I got banned from the admin and he said I had a bypasser. I spoke to him on team speak and told him about how I had never used a bypass before let alone heard of a bypasser before. He unbanned me and said if I use it again I will be banned. So my question is what happened I don't have any form of hack on my pc, I've never hacked before in my life. Please help will I'm scared to log back in in case I get perma banned. I've dont know what a bypass is PLEASE HELP

He's an alright guy, I just manned up and logged in and it seemed ok I still had my gear from before and stuff but if he bans me il just switch servers. Thanks for the help man
