Well, yeah. If they're just tweeting and not @ing at other users, they can't really "spam" anyone since only their followers, who choose to see them, will see those messages.

Twitter does take a pretty dim view of DM and @reply spam though because it is genuinely annoying and not opt-in.

Is follow spam targeted? Because most of my interaction with obvious bots is follow-churn.
