The Crazy thing is I bet you will still get promoted next season :P. Watch all this salt be for naught.
You were oblivious to the fact a player not on your roster can't play on your team. If you assume one will just take over the role with no actual confirmed knowledge of that, then you only have yourself to blame.
Could easily check strategy at the time you posted the player on the market, no?
Then also you saw you had lost a league game and decide to rage post about it 2 days after it had happened?
Also acting like a dick towards other players and the devs is unnecessary, it won't wipe away your tears or give you the win back.

From what I've observed, when inactive teams are cleared from the higher divisions, the system will promote the high elo teams that placed second in their leagues of the lower division.
P.S. I find it amusing that you omitted the 1 tournament game loss against that team in your screenshot ;)
