Well, your “Friend” was running a modded client with an auto-logger to continually log into the server. After being banned his client continued to log in repeatedly for hours. In addition, he is reportedly running PvP mods to fight for him while he is afk.

Soooooo…. There is nothing “unnecessary” about this. He will not be rejoining the server. And the last part was for the fact that his client was griefing staff with repeated logon attempts every 5 seconds after being banned. We were forced to unban him for a while so we could play and I banned him again when I logged out.
