I wouldn't be so positive about LSAC. Some enormous professional organizations with large operating budgets make silly mistakes like this. The real test of an organization is how easy it is to get them to fix such mistakes.
Dude. To underscore this point: ETS mis-scanned a bunch of tests back in October '06 (or maybe '07, I forget) and gave a thousands of students the wrong SAT scores, then tried to cover it up for months. AAMC managed to give med school applicants the wrong information about the tools that would be available on the first computer-based MCAT back in January '07 and how the tools would function, and while they were at it, gave students the wrong set of questions for a given passage (i.e. the questions on the right were not for the passage on the left but for a completely different, inaccessible passage). LSAC is known as a very good test-making company because they don't screw up very much, but everybody screws up sometimes.
So is it true? Heck if I know. But those of you who are saying that it's impossible, well, I don't think it's impossible.
The point isn't that LSAC usually does not screw up. It's that there's no reason to believe the situation is hopeless because there's some sort of underlying motive to denying this student a score. As I and others have said, this person simply has to demand to see the answer sheet or the statement he's supposed to send. It's possible that they don't have the answer sheet, but not likely. And if you believe, as I do, that LSAC wants this person to see the score, you can imagine that they will cooperate with him and try to figure this out.
There's always an off chance that something very unusual happened, but I don't see why LSAC wouldn't do what it can to figure everything out.
