Agree with you. However, Stamp is federated only for encrypted direct messages. The twitter-ish feeds are shared everything, and anyone can spin up a node. Anyone can post anything. Good luck taking it down from all the nodes.

That's the reason for the RPoW tokens, otherwise the platform would collapse from spam/DDoS.

Also, where you accept your DMs can move relatively quickly with the way the system is designed.
