Banned For Scripting

So I take a week break from league only to get an email today saying I was permanently banned for scripting, and I Look in my match history and notice 1 game that was played yesterday that I did not do, so I submit a ticket and they said that their system flagged me for doing it even before this compromise happened, now why would I script on a 8+ year old account and be in silver/iron at best?
