I was there when that happened. We were simply figuring out who is the one responsible for repeatedly crashing the server and because you came in recently, and never seen you before, we can only suspect those people that could be potential hackers. I'm sure the ban is only temporary so go ahead and try joining. If not, just ask Zero. And no need to stress out that you were banned for nothing. It was for a good cause to catch the hacker. Also, I am sorry that you had to experience that when the hacker showed up and ruined our fun.
