- It might just be random, but at 60 tries it's unlikely. Fun experiment: check the reviews of any game that uses RNG output. Drink when you see a 1 star complaining that the RNG is clearly broken with anecdotal evidence. (With 100k players playing 10 rounds a day, you're going to see a one-in-a-million event daily. (Afaik most devs make such games "more random" in response by increasing bias towards the mean.) That's probabilities on the order of flipping a coin and it coming up heads 20 times in a row (0.5^20==1/1e6 if I'm doing this 2am math right). Scaling that up to a 1 in 5 ratio, there's only a 1 in ~0.5M chance that you didn't see it after 60 tries. Of course, I have zero insight into what Imageshack is actually doing here, perhaps it excludes you for some reason (maybe it excludes the Bay area not to tip off the executives or their friends... for all we know).

- Perhaps I'm just wrong about 1 in 5 since my sample size was low.

- Confirmed from a German, Dutch, Argentine, and Belgian IP before posting this, all residential. I was indeed wondering if the person who initially mentioned this to me was detected to be in Russia or something since I didn't see it at first, but we all got it with varying numbers of retries; the Belgian on the first try.
