I'd love to verify this, but I swear there were times that massive hashing power was pointed towards mining on behalf of other wallets on the bitops - like they were gifting Bitseeds or something. I was refreshing the page periodically during the early mining stages when I was mining on Bitops and I saw some weird jumps in hashing power that didn't make sense. Wish I'd taken screen shots.
I observed this as well.
