I found this fascinating quote today:
It’s a problem for Twitter. It’s not that hard to defend against attacks aimed at gaming trending topics. After all, there are only a couple of them at any given time, and when the Twitter admins see a topic that’s obviously spammy or fake, they can just remove it manually. But stifling the creation of fake accounts is harder. If the trending topics and account creation turn into a never-ending rat race between spammers and Twitter admins who have to constantly remove them, there will always be some degree of spam permeating Twitter; hopefully it’ll never get so high to render Twitter unusable.mashable.com, 4chan Versus Twitter: Round One, Jul 2009
