I've known this for awhile. There was a time where you could get a rando whale upvote, a minnow booster upvoter, and a ninjawhale upvote all in the first 5 minutes of your post and get 100% of the rewards because the 100+ votes from all the trails would kill all future curation.
Curation Isn't working the way it was meant to work. I think a return to 50/50 would help.
