Got a reply from the support ticket.

I don't know what to do. I've been sick to my stomach over it and my eyes hurt.

The ban was for scripts, hacks, and such but I never have used a program like that. Even with third party programs, I have used ones that Riot itself said was okay. Like using custom skins and a voice changer. I've used Curse Voice a few times and read that it did something with league but I thought they patched that? Sometimes I would have to greenlight the game in my anti-virus and anti-malware because it would scan it as such, and then it would overwrite a file. But this is all I have ever done.

A while ago I did suspect some weird activity on my account and that was why I changed my password but. What if I'm banned forever?
