User blog comment:Raindrop57/Bloons Conception Wiki has been closed?/@comment-4519283-20131222011505

There are only three reasons for closing a wiki:
 * Founder request (unless there are other editors on the wiki)
 * Terms of Use violation (they would warn you first if it wasn't severe)
 * Copyright violation (which would have to be obviously intentional copyright violation with no attempt at changing anything)

Or it could have been a mistake.
