I banned you because you admitted to having the galacticcraft mod and refused to remove it because 'it took ages' to install in the first place. Even if you don't intend to use it, you can't have any mods installed other than optifine on this server. I can't have an xray mod installed and say 'I don't plan to use it' when the minimap is sitting right there on my screen. This rule is in place to keep people from cheating.
As soon as you can prove that you have uninstalled the mod, I will unban you. To prove it, take screenshots of your mod folder or take video of you force updating your minecraft. That is the only way you are getting back on here.
