Maybe that's only for some people.
I have a friend that is platinum 2 or 3 and some weeks ago he got offered bonus cash to do level 2 verification. First they offered 50$, then 100$ and finally 250$. As far as I know he didn't do it, even for the 250, hopefully for him the next mail to him won't be the one you got there. On reddit I saw several posts with the same bonus offers being sent to players.
To be honest, new players already have to do some sort of KYC just to be able to deposit. Making it kind of mandatory for existing customers was only a matter of time I guess.
Edit: I asked him and he got the same email as you, but with the 250$ bonus if he does it in the next couple of days.

I'm sure all non level 2 verified users received the same email, as I heard is that all users should be at least level 2 verified before 2025 Jan 1st but for the $250 bonus it is limited to this week only (till Oct 7th).
Frankly speaking, I'm jealous with the $250 offer becasue I did not receive any bonus when I did level 2 verification long time ago IIRC
Btw, as far as I can see on the last weekend stream, the number of online users was a bit less than it used to be.
With this mandatory level 2 kyc verification, will it also reduce the number of active players at stake?
Ask this because I still believe that there are still many gamblers who want to play without such a verification.
