teams in II that went bot have been replaced by new users
How could this happen? I thought new teams always start at the lowest level for a given nation, is this incorrect?
That was certainly the case and my reaction was pretty much the same as yours. At some point this season, it changed so new users were given the option to sign up for a higher, medium, or lower level league, though they can't be put into I if a lower option exists. The new users are "encouraged' not to choose the higher level option, though I don't know how precisely that was done since I haven't attempted to sign up for a team recently.
