(8.3) Spaminator contributes to a cleaner, more resilient blockchain. It encourages investment based on the confidence of users to invest in a blockchain that has a community-driven anti-abuse/security mechanism in place as a cohesive part of its ecosystem.
Spaminator itself does not generate any revenue. It is a not-for-profit project and its only purpose is to help better the Steem ecosystem by protecting the reward pool and mitigating the amount of spam and malicious exploitation.
