So I am closing this case by now.
Apparently LeooDiiaz!:3 were account trading or scamming with two people (Nipple and #DeaD'StronG!)
They are different players playing from another country than LeooDiiaz!:3 and they have private messages between them with some sensitive data.
Because LeooDiiaz!:3 was fully aware what he is doing and he also got a week to do the transaction or giving back the money, his penalty is a permanent account + serial ban.
Nipple gets temporary ban for the 700kk
The remaining 60kk is on Performances+ and #DeaD'StronG! accounts, they will lose this ammount of money (30kk each) but will also get a temporary ban.
The money will be sent back soon to Osmith0. when all three temporary banned account loses the money and they'll get unbanned.
