yo bro, same thing happened to me last week. i was typing "cheats on" as a joke in unrated and got hit with the *valorant banned for typing cheats* thing. riot's anti-cheat system is super sensitive now.
i reached out to support and they said it's automated and they can't do much. just gotta wait it out. maybe avoid typing anything sus in chat next time lol.
