Well, this is a dead thread but I thought I'd help out anyway.

What Russia did in the 20th century was called a workers dictatorship, and was meant to be a transition into communism, which is defined as a stateless and classless society. So, calling what Russia did 'communism' is a bit like calling what the fascists did 'capitalism', and then saying that because it didn't work, therefore capitalism doesn't work. Anarchists have generally stood against workers dictatorships because they seem to be an ineffective way of achieving communism, but they do want communism.

Soviet rule was at best state-capitalism, with the government creating market quotas, trading with other countries, annexing other countries for their resources, and ultimately still doing everything capitalist countries do, but with more state-intervention.
