Board Game Arena

No one else has noticed what this player seems to be doing?
He/she fattens her/his ELO with this account and then with CARKREY and all the other accounts of the same player (probably all of them with brazilian flag), he/she starts to lose to make their other accounts to move higher in the ELO ranking. Recently this person got 809 or so.
This is simply stupid.
GREAL: 0 victoires en 40 parties (0%)
CARKREY: 0 victoires en 36 parties (0%)
CANKRE: 0 victoires en 24 parties (0%)
Should I mind my own business instead? Maybe, but I think it is important to complain about this kind of behaviors in the community.
I reported the player, but BGA paid no mind it seems.

If you find something is amiss, just report the players.

I don't want to bother again with this, but the behavior of this player is really weird. After all his accounts were deleted, he's striking back with CONSULBORN, CAIUSKREY, KAKOKA and more recently NGKKRE. BGA is cool but this multiple account issue is disgusting.
