Even a simple Windows application which goes through ALL ID’s may be possible. 24 hours and any console worldwide would be banned.
This is the best bit of it! Ignoring all the zeroes on the sides from the screenshot, that's a 24 symbols long code in hex. That makes 7.92281625*10^28 possible combinations. Now let's say people work together and get 10,000 ID checked with PSN per second (not that the PSN is likely to be able to handle that at all). It would take about 2.5*10^17 years. Now, the age of the universe is estimated at about 1.4*10^10 years, and that puts this magical simple windows application in progress for about 18mil universe timespans, but then at last we'll finally have every PS3 out there banned!
So OK, the definition of may in this article might be a bit fuzzy. The definition of can now in the title even more so.
edit: actually calculated 16^24 isntead of 24^16, so that puts it at only about 3 universe timespans. Everybody start panicking.
