Hm, interesting. It might be worth a conversation to see if we can assist with this at all. The CAMPUS system could well support something like this with multi-proof-of-brain. For me, building a system that weeds out spam (and ultimately makes it a pointless waste of time to produce spammy or plagiarised content) is something that's worth putting my energy into. We've started with CAMPUS, but now, I think there is a lot more we can do. I'm toying with the idea of building in a spam hammer, because I'm sick of the large amounts of shit that's on the promo-steem tag (as well as others). Perhaps there may be a useful collaboration which we could work on?
