Should Riot look into accounts that were wrongfully banned?

In rare cases, league of legends accounts get hacked into by another player, and the account gets banned. When the original player comes back, his years of leveling up, ranking, and mastery gets removed in a second. So here is the question: should riot look into accounts that were wrongfully banned? Is there anything that riot can do about it? Is taking that much time to look into such a thing really worth it for the small amount of people actually getting innocently banned?

Keep in mind that these cases are rare, and many people who were actually toxic and being *ssholes in game can also claim that their account got ‘hacked into’. That is wrong, so how will riot be able to tell the difference? Can riot even do anything about this?

I would love to hear your ideas down below!
