My Brother Got My Account Banned For Toxic Behavior.

Well there are these rules about account sharing...
You wouldn't happen to be grinding ranked on that account possibly?

Highly doubt you can get the ban lifted as account sharing is violation as it is. 

All in all sounds very brotherly thing to do. 

He was using my account without my permission. and I don't allow him to. can i do something about it? i really don't wanna lose my game progress because of this.

Yeah but getting banned from all ea products is harsh and not fair. Especially for something that you didn't do..

Yeah, you're right. That's it then, years of progress and tons of money went to thin air i guess.. thanks for the help.

Sorry to hear that.

However account security starts with you. Protecting your passwords, Ensuring that you have logged out so that others cannot use the account, ensuring that every time you log in the passwords must be entered so that others do not auto log-in, Sharing of accounts is against the ToS. 

See the Bolded items below.

Account Safety

How to keep your account and hardware safe 101:

1. Use strong passwords for you game account.
2. Use strong passwords for the associated E-mail account. Keep track of your e-mail accounts and what they are connected to.
3. Do not share either of these passwords with others. Keep note of your passwords in a safe place.
4. Enable two factor identification for both the game and associated E-mail accounts.
5. Do not let others use your game account (Friends and family alike) because if they do something wrong on your account it is still your fault, nobody wants to have a sanction on their account because somebody else did or said something wrong.
6. Do not use internet café’s to access your account and play, you do not know what software is on the hardware there, you do not know if the hardware at the cafe has a hardware ban and this can affect your account in a negative way.
7. I would suggest only accessing your account with your own trusted hardware, gaming on another person’s hardware brings some of the same risks as above.
8. I would also suggest not letting others use your hardware in order to play with their account, because if they get a hardware ban on your hardware while using it, it can have a negative affect on your account.
9. Buying used hardware comes with risks as well. The hardware could have been banned and this is not an EA problem but a problem between the buyer and the seller. 
10. Play nice with others, in other words do not de-mean, harass or bully others in Chat or over voice coms, both can be reported and that can also have a negative effect on your account.
11. Use non-offensive user/gamer tag/club tags, if you get a warning about such change it, doing otherwise can lead to a negative effect on your account.
12. Play fair, boosting and teaming are cheating.
13. Play fair using cheating software or hardware is not fair and is really only cheating yourself.
14. Do not buy and or sell accounts, do you really know what has been done with the account? What cyber info are you giving up? What risk is there that the account is bunk. What is the risk to your hardware?
15. Re-read the Terms of Service agreement and the Terms of Sale agreement you agreed to play this game and adhere to it. https://www.ea.com/legal/user-agreement and https://www.ea.com/legal/terms-of-sale

About points 7, 8, and 9, I do know that not everyone can afford multiple hardware setups for the entire family and there is trust that has to be there, talking about the does and don’ts on the use of shared hardware should be done so everybody can enjoy what they do on the hardware and everyone can be safe.

If you believe you have been hacked take appropriate measures to secure your account and associated E-mail account https://help.ea.com/en-gb/help/account/secure-hacked-ea-account/

If you believe that a sanction (Suspension/Ban) placed on your account was by mistake you should reach out to the Terms of Service team https://help.ea.com/za/help/account/information-about-locked-or-banned-or-suspended-accounts/

Thanks for the advice but it's too late for that

@PixLead 

It is never to late for such advice and Cybersecurity awareness. 

This stuff also applies to your e-mail, banking and social network accounts, not just gaming. 

Remember it for the future, keep all of your accounts safe.

Although you are right as it applies to your EA gaming account.
