On the FAQ page it says that entering with multiple Blizzard Accounts isn't allowed and invalidates the entries, if you've already purchased tickets you're not allowed to opt-in for additional ones, and you can only purchase two tickets if you win the drawing and not 5.
It doesn't invalidate them, it removes the dupes:

Does having multiple Blizzard Accounts created before 9:00 p.m. PDT on August 12, 2008 help my chances of winning tickets? No, the selection process will screen for multiple accounts registered to the same user. Any duplicate entries will be removed from the selection pool at the time of the drawing.
Bad wording on my part, I meant it invalidates any extra entries so you still only get one shot just like everyone else. It doesn't invalidate ALL of them .
