i got banned for x-raying and I'm not denying it, but i got banned permenantley. is this a mistake? or is it not.
if it is i accept that.

"http://www.opticraft.net/index.php/topic,5842.0.html" here it says:
"4) Not correctly entered (sometimes a moderator will mistype the ban command and accidentally make a ban permanent)"
which is where that idea came from.

"http://www.opticraft.net/index.php/topic,3.0.html" also at the server rules, it says:
Server rules

    No griefing (Destroying other players work)
    No vulgar drawings
    No excessive swearing or abuse. (Swearing is OK)
    Absolutely no harassing or abusive behavior to other users
    Hacks are ALLOWED
    Be courteous, ask if you can help someone before working on someone else's creation
    No towering or creating ugly structures.
    No bots whatsoever
    No advertising other servers
    English only in public chat
    No reserving of space

so would x-ray be categorized as a hack, considering hacks are apparantley allowed.

A few weeks a go I tried to log on to "smp.opticraft.net" but every time i try to log on it just says
"The ban hammer has spoken!". But the problem is I have no idea why i have been banned.
Could someone plz tell me what i did! sorry for doing whatever i did! Thanks!!   :-)
