How can Riot tell if a permabanned "banned on sight" player is reformed? Example Jensen.

I mean since he couldn't have played any game to prove that he wasn't toxic anymore, how DID he proof it? Did he have a talk with Riot, what made them ultimately lift the ban?

It definitely was the right decision, he is one of the best midlaners in the western scene and there's no doubt that he's reformed, I'm just interested how exactly the decision was made.

Also makes me think about other permabanned players. Tyler1 seems like a player with a lot of potential if he stops being toxic in game and reforms, whether it's as a streamer or as a competitive player or even both.
