> One solution this decentralized server system came up with is the concept of accounts that have some barrier to entry to create (which involves a delay and proving identity). This account has a private key and it uses this to access the servers through any IP. Abuse on this account and any connected accounts of course leads to the key being temporarily revoked. Lots of positive interactions with well established accounts increases your credibility. Lots of reports decreases you credibility. That's essentially DKIM being fed into your average domain reputation system.
