How do you know what they are claiming? Are you them?
I have highlighted the bits that may be important.
Guys make sure you check your bets, I found a flaw in the seed. I kept seed numbers and results, if anyone wants to help confirm this on PM.
Even if you make the leap to assume that "flaw in the seed" means "I have the server seed and can win at will", why would someone (a) post that here; (b) suggest to check the bets?
Do you posses other information on the subject?
