The #1 rule of building in crypto: 

⚔️You will be Sybil attacked

After a few instances of possible collusion in our early predictions, we implemented an advanced ML algo that incorporates cluster analysis to protect the integrity of the game.

Votes from new users have significantly diminished weights until they’ve proven that they’re voting in a non-collusive manner. We can identify clusters that share similar characteristics and always vote in a statistically anomalous way. We then diminish their votes in weight until they start to trend outside of their cluster. 

The major benefit to this approach is we don’t have to ban people, and the weighting will never affect earnings if your intuition is right.

Here’s a little diagram of how it works.

this is cool, bookmarked. i was wondering how much price plays a factor into this (e.g. 50cent ponder predictions, x dollar warpcast invites) and went down a rabbit hole - sharing here

Nice, this checks out - I always wonder how much high level thinking the international groups do, or if it’s more of a gut feel. I’d guess more scientific over time.
