I was banned by EA for no reason,why?

For a newcomer who just entered the game, I originally thought that this game has high quality and strong operability. So I started this game on the day of the steam discount, but it only took me from the successful purchase to the inexplicable ban. For a few hours, from the beginning of my game to one minute before I was blocked, I didn't know what I did wrong. Am I a hacker? Insulting others? I still did something wrong, but in fact I didn’t do all of this. I just played in the story mode for a while and then played a few attack modes. I was about to quit the game and suddenly I received a unilateral notification from EA to block my account. The reason is that I violated the user agreement? I'm really confused. I was ruthlessly rejected by EA before I even had time to understand the general content of the game?

If the official staff can see this post, I hope you can answer the situation I encountered and deal with it responsibly. Don’t let the error judged by the detection program disappoint the players and I will cooperate with the official staff to review and supervise. Please do as soon as possible I handle it, thank you.
