What makes me curious is, what the reason from the hacker to hack unpopular site like sicodice?
Money? I do not think sicodice has good amount of money (bankroll on the hot wallet) so I think it does not worth for the hacker to hack sicodice.
High likely, it is just a trick from the owner to run away with people's money and made a lie that the site has been hacked.
I have no account in this site, do they have official social media accounts?
Hacker wants their money obviously. Your opinion might be the reason, but it's also can be another reason. Unpopular site being targeted because their site still full of bug , so it could be hacked.
For unpopular dice site i doubt they even have.
