I was banned for rejoining after being kicked for AFK for hacks. I use my computer with Minecraft active in the background while doing other things and occasionally check back in to either jump or rejoin, I have never used hacks.
It was really suspicious how you stood there and rejoined after everytime you were kicked to test for AFK. You never responded to use when we tried talking to you in chat. If you want to appeal and try to come back, create a ban appeal here. https://www.mc-realm.com/forum/m/39067230/viewforum/9404606
The page you linked says I don't have sufficient access to view it. As for not responding to you, as I mentioned before I have Minecraft open in the background. The moment I click join I go back to what I was doing.
