Someone is probably trying to scam you.

It usually happens when you start complaining about not receiving huge amount of money and you share your email and telegram in public. I think you will get more of these messages, you should probably move to new email and phone number.

Of course, don't send money for "account reactivation", makes no sense.

i contacted the OP (ginalli) to ask him few questions (of course not private) and seems like cloudbet is asking for bribe (cash under the table) to unlock his account from what he says.
correct me if i am wrong but we seen that before..
casinos locking people account to milk money from the big players, and in the end after the big noise, they always do that and milk their players.
this is classic case and not something new...
sadly the amount is big this time
