The ones pushing the hacker theory is Slotella.com. The op is adamant that he wasn't hacked and has consistently accused Slotella of being the culprits.
According to Slotella the account was accessed via a different device/region from the op’s:
When we check the logs, you were logged into your account from a device different from the region you are in. First you or someone else activate 2FA verification then playing Wild cash game.
Here they also pointed out the op used a very weak password.
This is really the first time we've experienced it. There are only two possibilities on our side.
The first possibility is that the player's account has been hacked. It doesn't have to be a remote attack. It might be someone who knows him because his account logins only show up from Finland. (Same region as the player)
We checked the password change actions for this suspicious process. According to an IT security expert, the player's password is something like asdasdas. I really don't find it logical.
If you have such a large amount in a casino account, your account password should be stronger(instead of asdasadas) and you should enable two-step verification.
So why is Slotella lying?
According to them In the first quote the account was accessed from a different device/region, but in the second quote they claim the “hack” occurred from the same region - Finland. Which is it? What is the truth? Why the inconsistency?
Regarding the op’s attitude, I'd be mad if I believed I was being scammed for such an amount. €90k euros is a life changing amount of money for $99% of us. And people say all sorts of things, even to their loved ones, when they’re angry. We’ve seen it happen on this forum time and again, where victims angrily say they are only interested in exposing the scammers and not recovering the funds, only to backtrack later.
