There are de-facto communities in Twitter, so that still exists. Like, if you follow municipal politics you'll see a very consistent list of names and faces, for example, since that tends to be a pretty small sandbox unless you live in a huge city. Blocking is a poor substitute for down-votes and moderation, but the trolls will get blocked and frozen out of that pseudocommunity.
