My account got hacked, when I was away for 2 years for studies and that person who hacked my account, got my account banned. So basically your account is completely unsafe anyone can come hack and get you banned. This is the message from support
We take account security very seriously and we're constantly working on improving it. As you already know, you have the option of creating a new account. However, this is your personal choice.
I understand you're disappointed with my answer, but the decision is final. :( The suspension will remain on the account.
Good Luck out there!"
Good Job Riot thanks for making my absence my fault.
