Some miners try to save a tiny amount of time by "spying" on other miners. For example they connect a fake miner to the other mining pools and as the other pool finds a new block their fake miner receives that "hash" of that block which is small (32 bytes only) then the "spy" miner builds their next block based on that hash alone without verifying if the block that was found by the other pool was valid or not (which it may not be valid and during a upgrade/fork the chances of it are higher and that would create a longer stale chain with 2 blocks in it, if more miners do the same this stale chain can become longer).

Do miners do this to try and get a head start on finding the next block and getting a reward? Do these empty blocks live on the shared blockchain if they don't become stale?

I've seen luke on reddit getting angry at laymen for not understanding complex coder concepts. Seems like a nice guy /s
