I've got banned from Apex Legends

Got greeted with this message today. I've been playing Apex on linux for more than a year. Not sure if this could be related? Is this just me?

I've contested the ban and I'm currently waiting for a response from ea support.

UPDATE : Got an email response from EA today. It's basically a generic message saying that my account was associated with "cheating practices" and so they will not remove the ban.

This is absolutely fucking ridiculous! I've been playing this game since 2020 and have 3K+ hours on record, now this shit happens and there's no recourse ? Fuck this company.
