Yeah. I was assuming it was in a latin alphabet but I was wrong. I just read the paper, it was in a klingon alphabet, so essentially arbitrary symbols. So my guess was wrong, it's difficult to see an explanation here that makes any financial sense. Apparently they concluded that they were other researchers? I suppose you could imagine the results in some sort of auction system that ended up paying a lot (more than they were making) for problems no one else was willing to solve. But that doesn't seem too likely.
