Thanks for you quick response. Better you play from your initial account "Odnoobraz_bcm". A user can´t switch accounts in the middle of the season just like that, as otherwise I have no clue who is playing and don´t want to request identification. Happened also to @rodrook.
By the way, there were always rules about multiple accounts on lichess saying this is not allowed. Maybe for titled players there are exceptions, but 6 different accounts seems excessive.
