That makes sense. If everyone did that, the network would continue to get better. My assumption was that most people are decent and not spammers. There just needs to be a way to filter out the worst and make it difficult for those new spammers to just blast the network using automated bots. It would be a hurdle to get your bitcoin followed by decent people and presumably a bigger hurdle to stay followed after the bot starts spamming. Anyway, just a suggestion.
