ashkan176 has been removed for the 6th round before starting as you'd adviced me. For the fourth round this player lost both games by time and now he closed his account.

As it is only the first round, we can let people be just warned.
In future rounds I hope to be able to make warnings before the round actually starts and give the possibility to remove multiteam players.

Bonjour
Tu joues deja pour Bordeaux dans cette compétition,tu choisis,ou tu abandonnes ta partie contre Moscou avec Toulouse ou tu abandonnes ta partie contre Kiev avec Bordeaux
Strange....
Anyway I did in time, you can see on the match site. You removed two players, and I wrote immediately that there is a third one, too. You wrote sorry, i am right.
"Too late?" Where are a half sentence about the time in the rules? Again I ask something, and I do not get answer.
I try again... Who is the multiteam player? What is the penalty? Andrey-25 is a multiteam player?
Why he is not in the list with the 552362 match?
Now I see. I did not remember that case and the question.
Yes, you did report him. OK, he is a multiteamer.
But I don't think that we should recount match results for ALL those guys - and we should not ban them from play. They just have to choose which ONE team they support.
The tool now can warn us giving a big picture. Earlier we could not see it.
