I have also been banned from Battlefield 1 and Battlefield 2042. When I asked what it was I did to cause the ban they just reply with "you violated the anti cheat or user agreement" and so far they refuse to identify what it was I apparently did. I haven't played BF1 since the end of 2023 but was somehow banned on July 1st of this year.
I wouldn't get my hopes up. They seem extremely unfair and it must be too much of a tedious task for them to actually review it and unlock the account. I've been disputing this since the start of this month and I'm still waiting for a half decent response
