Obviously it would be impossible for OP to give proof. What would exactly qualify as proof? It would be impossible for PD to post proof too. They could show proof that the IPs were different, but that could mean either compromised, OP on VPN or in theory PD employee. So not really proof.
I don't know OP at all. But I did see him in another chat and I do estimate that he is telling the truth here. That being said, with the trust record of PD, I also think they tell the truth.
Overall, one of the most likely reasons still seems a phishing site to me. I told OP that before, but I just want to emphasize that being on iOS doesn't help against phishing. You could have google-ed for PD and clicked a google ad on top that links to a PD phishing site. Or you could have clicked some link in a chat that linked to a fake phishing PD site. Although I am sure you disagree with this theory, you could perhaps check the browser history for all sites you visited?
BTW, the policy of not refunding compromised accounts is an obvious one. You have to understand that this would open up opportunities for scammers to claim the same thing. I am absolutely not saying that you are doing that, just explaining why they cannot really give refunds for that.
Still.. trying to find the cause of the (potential) compromising, seems good to me. GL and sorry for loss, either way.
I lost 0,3 btc on primedice as well,the instant the money showed up,someone withdrew to a different bitcoin address.
My computer is safe as well as my password.
Also,I'd like to say that this is the first time I visited PD,so I could not have fallen victim to phishing attempts.
I decided not to pursue the matter further,because the amount that I lost was trivial.However if I had lost 13 bitcoins,I would be pretty pissed off.
Anyways what the guy I quoted is saying is pretty on spot,I realise they cannot do anything,because this is the internet.If someone genuinely gets his refund,then 50 more cases will popup,falsely claiming that they were hacked too.
Also there is not definitive evidence on either side.
There's a wise saying that says "where there's smoke,there's fire".Multiple cases of people getting hacked are not random and isolated incidents.
Something is up with primedice,and I would strongly suggest protecting your account.
I would like to wish good luck on the OP,however i'm not sure primedice can do anything other than making sure their website is 100% safe.
One final thought,is that the "scammer" probably isn't affiliated with primedice.A website such as theirs,makes tons of money every day,so it would be obvious that risking the site's reputation is totally not worth it on the long run.
