Honestly I'm curious what type of "proof" you'd want beyond what was provided.

Of course i have read the story.. First of all Medium.com is not really The New York Times..
Secondly, the story is just so well written with so much details and sources and i find it very ironic that a casino who has lost a million dollar would care to put so much work into writing a story like this. (If a bank gets robbed we dont really see the bank publishing articles about the specific details of how the robber exploited their security)
Adding more to this.. i actually find the story partially praising the hacker's talent as so you call it, encouraging other hackers to keep doing the same
And yeah what particular proof can you exactly give to authenticate this story ? Blockchain is just too vague for that. But please dont tell me txids are your proof.
I believe the amount of publicity, wager and profit PD seems to claim the have achieved throughout the years, they should go public with their detailed earnings & proof of legal ownership of the site.
Additionally all the admins, developer and staffs who work for PD should be publicly verified and not hide under cheesy usernames like Micro & Stunna.
Hufflepluff story is just an example of how vague Primedice.com is behind a fancy article
