They don't technically need to have all the "85 rouble party" crowd to do the voting before deciding anything. It's not how wikipedia works.
Besides I don't understand what wikipedia did wrong.
About Wikipedia. Do you still remember the SOPA blackout day? Everybody was warned about upcoming blackout a few weeks beforehand, and most importantly, pretty much everyone supported the blackout, thus reaching the consensus. http://en.wikipedia.org/wiki/Wikipedia:Consensus
Today, Russian Wiki is closed. The decision was taken yesterday by a bunch of admins, who started a poll, without any warning and without anyone prepared. It is a violation of consensus rules as described in the link above: "Consensus ... nor is it the result of a vote."
Admins' actions today are a blatant violation of these rules by Coordinated actions, Meatpuppetry and are biased in general: http://en.wikipedia.org/wiki/Wikipedia:False_consensus
