From what I can tell, it seems that a couple of us also got emails from EA asking to change PW because our accounts were apparently compromises. I am pretty sure it was what triggered my ban, and overturned it.
People who got banned, check your spam folder just in case you got the same.
Maybe we got something here. The night before I got banned, I played with my mouse dpi in Logitech G Hub, overlays with Geforce, etc. There was multiple causes on my end with the mentionned programs too. I also think we need to investigate more by gathering that info!
