Spam teams at social networks typically shadow-ban spammers. The goal of this is to make it as difficult as possible for the spammer to determine that they've been caught (which is why I think the frustration techniques, or simply account suspension aren't widely used).
The field of spam-prevention is fascinating because it's essentially an arms race between companies deploying tactics to detect spam and sophisticated spammers using increasingly complex methods to avoid detection.
So there's an advantage gained by companies if spammers believe they don't need to evolve their methods.
