A lot of complaints about Wizchan are really complaints about vichan
is it deliberate or not tho
Yes. Vichan and its upgraded version NPFChan offer an out-of-the-box user board creation option. Because of this, boards don't share resources. A thread in board X with resources stored in the asset folder of board Y could be ruined if something happened to board Y. Just duplicating things simplifies file management down the line for the admin. No sense having to consider if an old asset may still be in use somewhere when the original version of the thread has long since 404d.
