So I just noticed something interesting. Not sure if it is related to the ban or not.
I've downloaded all my GDPR data from EA and it states,
"Status_Reason": "SUSPENDED_MISCONDUCT_GENERAL"
I am feeling a bit conspiratory in the matter, as I know I am clean the only thing that could trigger this is either a hacked account or someone from EA reacting to my negative Steam review and doing a manual ban on this.
I've requested further GDPR/PII from EA, will see what the response will be there. I am seriously considering legal actions in the matter.
For now, could you all request your data from EA and verify the Status_reason?
