For anti-bot / reputation systems, I think there's some value in the type of proof of space and time (PoST) algorithm used by the Chia blockchain. Algorithms that do proof of idle resources switch the economies of scale so it's cheaper for the average user to participate in a system than it is for an industrial scale botnet or bad actor. IE: Scaling up costs real money while I have a ton of idle capacity sitting in front of me right now that I could use for proofs with an incremental cost of $0 to me. Reputation and identity are ripe for disruption IMO and systems that prove idle capacity for a period of time are pretty interesting and in their infancy right now.
