I think you missed this part , I'm not saying that we can perfectly keep safe from hacker but with OP has a complete understanding about the system?
By the way, I have never been hacked at any site in my 20+ years online, and I am a professional IT security manager
And what does that part prove?
I have an experience of 25 years in neurosurgery, 30 years of flying military aircraft, 20 years of experience in a bank, 40 years as a farmer, and of course 300+ years as a Jedi. Anyone can claim anything here, without proof those are just claims, and even the fact that you haven't been hacked in 20 years doesn't mean at all you're "unhackable", again you're playing on a platform, there might be flaws on that platform which are unknown to both user and owner.
Actually I’m in favor to OP this time, A hacker will not login someones account and bet randomly huge bet to slot just purposely lose the balance, If I where the hacker, I will wait until the withdrawal is already cooldown then setup 2FA and withdraw the balance.
But on the other hand OP make it looks like a hack by using VPN and bet huge amount on buy bonus and use this thread as insurance when he loses since I realized that all the following bets are made in buy bonus and not on regular spin which is known that OP do a buy bonus with amount based on his first win.
So which one is it?
There are two real possibilities here, and the hacker issue is having zero chances
- the casino did that, locking him out of the account and playing in his place losing his money
- the OP made it look like somebody took over his account so if he would lose he could blame the casino
Normally I would side with the player on this one but his attitude where all he cares about is shouting that the service is a scam and making no real attempt to solve the issue, bragging about his own status, calling other degenerates, and so on makes me tend to believe is the second one.
