League Manager Dishonest

I actively participated in a championship in which I had already raced in the past but only as an off-line.
I have won many races and the title had already been won a few races before the end.
Nobody ever complained about my supremacy (which embarrassed me) with me or on the championship bulletin board. 
I would have gladly continued my experience there but there was a problem of overlapping time with another league: I kindly asked if it was possible to change the duration of the race, but I was told no.
Tonight, a few minutes before the start of the last race I was kicked out by the championship manager. 
I came back and he chased me out again.

I asked him for explanations and he said that all the players had complained about me and that I change championships too often and therefore he would have anticipated me. pity that I would have done it after the last race. Afterwards he also made fun of me saying "ok boomer I will not do it again" .

I must add that he complained, on his league page, that he had received "death threats". I have no reason to believe such a dishonest person, but in any case I did nothing but assure him that he would pay for his bad work, exactly what I expect here. it would be very welcome if my palmares were updated to 10 championships won and 100 reputation points were added. at the basis of my expulsion there are certainly reasons related to my non-French nationality and the fact that I was not part of the administrator's friends. who won, thanks to my forced abandonment, the championship also mocked me.
Similar episodes make it difficult for me to stay on this game.

This is the link of the league

This is happening way too often. A set of standard protocols must be attached to all new and sent to existing League Hosts outlining the do's and don'ts.  And really, there needs to be link where all league's players including hosts can address these issues privately.  

I know there are a lot of ways to contact moderators and igp support. What these issues ask for is a separate department to answer and settle any issues deriving from ignorance and/or lack of game-know-how understanding. 

The matter has been settled internally. I'm closing the thread.
