Of course it's better and more convenient to save "Odnoobraz_bcm" and play from it, but it's now closed, and all depend on Lichess administrators and moderators.
I was aware of the Lichess rules about multiaccounts, but it was never a strict and unambiguous prohibition. Previously, the rules even specified approximate situations: exploring a new opening, playing blind, etc., and it was said that administrators would make a decision on a case-by-case basis. So I've never hidden my accounts, as well as the reason why there are so many of them: a limit of 50 teams per account.
