It is not the first time I have seen this error, they have made the same warning to the new accounts just because of the Red Flags by the system.
Usually, it is an alt account and bonus abuse case, it is hard to prove that you don't abuse any promotion.
They count affiliate earnings as profit so many high-rollers open new Bc.game accounts to farm affiliate rewards.
BC.Game team has made this decision to prevent bonus abuse but you can email them or pm the representative account to explain the situation.
That warning is not correct anyways, it appears when the system permanently closes your account which is hard to recover. If your rank was higher than level 38 it is worth spending time on the recovery process, IMO.
I already saw this warning after I logged-in in my Gmail account but I never experienced this in any of my gambling accounts. The OP can just follow the instructions given to him and that should solve his problem. If not then he can post on the ann thread of BC.Game in this forum which are located
here.
This problem can occur not only on the newly created accounts but can happen too on old accounts which password is weak enough and easy to guess. It's better to create a much stronger password and then enable 2fa's for the safety of our accounts because there are so many hackers now lurking around. If it's about abuse then the account will be insta ban or the warnings will look differently.
