Hi Matteo, just some thoughts from my side:
You say you had this rationale just for your last two videos. That means you did not upload your first three videos, as you say, “out of laziness”. That also means you were already removed after the third missed deadline. It did not matter whether you uploaded or not uploaded video 4 and 5 because the rules already set those to 0-4. That Simon Orton only recalled a bit later that three missed deadlines means removal is not significant.
Being removed has the consequence that all matches are set to 0-4 which automatically means that that person has last place in their division (red spot). And a player on a red spot is relegated, without the chance of a relegation match.
I feel that is also a reasonable consequence:
If there was a difference between removal and just placing last, a player could always make an “escape into removal” if the season does not go well:
Let’s say someone has played all their 5 matches and they are last based on their results. In addition, they have already missed the video deadlines for match 3 and 4. If removal would mean one could stay in their division, a paradoxical situation would ensue:
If the player does upload video 5, they are relegated to the lower division. But if they do not upload video 5 (= break the rules), they are “only” removed and can stay in the league. An absurd consequence.
By the way, for those div. 2 players worrying about a stronger player in their division: whichever subdivision has Matteo in it will have two green spots (direct advancement to div. 1) instead of one and also the usual yellow spot (relegation match between div. 1 and div. 2). That means from your perspective the strong player basically has no consequence, you will still be competing among yourselves for one green spot and one yellow spot as usual.
As a final note, checking videos and asking people to upload is quite a lot of work for the supervisor team, and not doing that disturbs the whole process and also creates a competitive imbalance in the division itself (which, I think, lead to quite some discontent in div. 1b). To my understanding, that it why the line is drawn at 3 missed video deadlines max.
I hope that perspectice was helpful. It would be great if officials like @Simon and @Hannes could chip in.
