@Crashy_v A mod or higher can only ban a person if there is proof, else it's a warning or under investigation. If u were banned they have proof to assure u, u where using modifications at that moment.
In case u are confident u didn't use any mods, u should make a ticket with proper manners and not attack anxii for doing his job.
Be sure to add any evidence u have to proof u didn't hack when the ban was placed.
