English: Bulgarian dialect map in the early 20th century. This map does not differentiate areas where Bulgarian is in the majority from those where it is in the minority. North of the Danube, the additions of Maxho and Nihil scimus are into line with available sources. If a contributor is considered a sockpuppet by other contributors in the context of nationalist controversies, this does not prove that he is systematically and necessarily wrong. Technically, only the map creator Magnus Manske has the ability to revert Maxho without touching Nihil scimus.
