although this strategy has been discussed, one shouldnt always rely on it, making this 'virtual keeper' makes you lose a spoiler, so now you have one, and the opposing alliance has 2, even if you use this 'keeper' to make a long row, opposing alliance has a better chance of spoiling it with two spoilers then you would have of spoiling their rows.
good strategy, but i dont think you will see it used commonly
