I agree it's a hard problem to solve, and we've got no illusions about that.

This post (also, coincidentally by Vitalik) talks about different levels of collusion (from unsophisticated to sophisticated) https://vitalik.ca/general/2019/04/03/collusion.html

Gitcoin's approach thus far has been to stop collusion from unsophisticated actors, then progressively get more organized (as more money gets involved, and as we learn from each round) about stopping collusion from more sophisticated actors.

This thread talks about some collusion that we founnd in Round 5. https://twitter.com/owocki/status/1250097472694702080
