Look into preventing two stakes from landing on the same block #3
To try and combat "collusion" through flooding stake requests. By preventing initial stakes from landing on the same block, a malicious pinner can't drop transactions at the same time by the same participant to try and outrace their competition to lock down the pin for themselves.
Not fool proof, but the network fees, plus the risk of losing their initial stake, plus the less likely chance of staking the same bid, should all make that effort not worth it for bids with a reasonable value.
