Pointless and irrelevant comment.

Every work sent to every miner, about once every 30 seconds, says in it what pool the block is for and the address it will pay to.

If you think that pools are randomly changing this and no one has ever noticed it, you clearly have no understanding for how mining actually works.

Anyone can look at the work they are mining, and you can even watch it go by with a network monitor program - in ascii for the identification of most pools.

When a block is found on the network, it will contain that text, and everyone on the planet will see it, so know which pool found it.
That's how all the block explorer sites work.

It's a ridiculous scenario you you seems to want to be true, and though you may find common in the scam coin section of the forum, not here on this pool that has been around for almost 6 years.

The miner itself will also know it has found a block, so I guess you think it's a game to try and hide a block and hope no one will notice?

On top of that, mine is also the only pool that immediately reports blocks on the web site and to all the miners, even if it is stale, orphan, rejected, valid or otherwise.
You can see the original code for that in the public git.
Even ck's fuck up recently would show up as a block on my site, if the user was mining here, and I was stupid enough to allow the bitcoind to get behind on the network - alas however, that stupidity wouldn't happen here.

Trying understanding something first ...
