First about trying to recruit outside support in revert wars it simply does not work I mean it may work for a day or two perhaps a week even but few of the recruited users actually stay and those who do were likely to come here anyway A relative small minority of Ukrainian or Russian or Polish or other E European public can really contribute to enwiki as this requires individuals with a huge interest involvement good internet access relative wellbeing in RL one is unlikely to be able to commit time to the project when one really struggles to put bread on the table has to battle health problems and other real life disasters good English etc etc etc As you see this limits the pool of potential contributors to a very small segment and posting calls at internet forums will unlikely affect the number of the users who will stay  About nationalists all nationalists have a hard time at Wikipedia and most longterm users are those with moderate views Strongly nationalist editors find themselves in trouble soon enough and I am familiar with several instances of Russian nationalist users ending up banned or having left due to frustration Wikipedia is a more welcome place to moderate editors be them Ukraino Russo or Polonophile Contrary to your assertion there are several actively working Ukrainian editors right now and they manage to not run into any trouble And there are also users who manage to get in trouble all the time Now to the user in question I would agree that he is somewhat exceptional in that he may be called a Russian nationalist indeed and he gets in trouble only on the very rare occasions However the important distinction is that the users activity in Wikipedia goes by far beyond picking and fighting the nationalist crusades and running endless revert wars User contributes a whole lot of content to the project and some topics of his interest and giant contributions have no relation to the nationalism whatsoever There is another thing though which makes this user different from his opponents he mentions in the link you provide In the UARU conflicts where the user is involved he does not scatter the general hatred towards the Ukrainians something that his opponents do all the time in their talk page entries and edit summaries   I agree that when sides blame each other all the time mutual animosity and distrust is inevitable Point is that only a small part of each side play this game and the rest manage to get along without developing the hatred and distrust
