Has anyone succesfully argued against a ToS sanction?

@Spicybeefburps Always try, but chances are slim cause you'll get the same cookie-cutter email stating they got your claim and investigated again but still found you cheated.

If you ask how they investigated you'll not get an answer to the question or get the response that they can't divulge the method.

Good luck tho

I helped a lot of people here and yes some get their account back but appealing bans is not something that I follow up that much.
Something that can improve your chances of a successful appeal is to give as much information as possible.

Know that EAC not only detects Apex Legends cheats but can trigger if any other game cheats or mods have been installed.
I understand it feels a bit unfair that you cannot talk directly to a person and would frustrate me as well but this is the method ban appeals are handled.

Maybe providing more information could lead to a different result?
You can appeal multiple times so give it a shot.
