Yep darth vader that's the point of Googlewhacks - once you've found them and posted them, after Google has done it's next metacrawl over the page, they're not Googlewhacks any more. That's why they can only be your Googlewhacks and no-one else can claim them.
stf42It's a bind about dictionary.com, isn't it. I think the reason it's used it because that's the dictionary that Google checks with (you know when it tells you if it thinks you've spelled a word wrong).
jenstar, the official answer from the official site for you is: I understand the theory that since word lists shouldn't be counted as a whack, they shouldn't be counted against a whack. (It's a logical extension of the theory that when you find money on the street you should keep it, but when you lose money on the street everybody else should give it back to you.)
However, our Whack! script has plenty to do in verifying both the existence of just one result, and Google's recognition of the dictionary.com element. We've considered checking for word lists, but it's not entirely trivial. So, you'll just have accept that if you don't actually do something, you won't actually get credit for it. Sort of like... real life.
