SPR is no a solo-mining(decentralized)coin any longer
Wrong.
So you are the owner of that pool and you confirm that SpreadCoin can not be pool mined? What for is then this pool? Is it only for trusted miners?
Correct, it is
extremely unlikely there will ever be any other pools, this was merely a test to that.

Hope everybody was able to collect some more on the dump, because it won't last long
