How bannable are referral and smurf accounts?
I just got friend which apprently had more than 100 referrals (because he had the unique WW skin), he got his skins removed and Riot points taken back. He also got denied by Refer-a-Friend program. About how bad is it to have fake referrals as by Riot? If you have 5 fake refferals you're much safer than you have 50000 fake referrals. But where's the limit, where YOU suggest to put limit on? When does Riot look at your really harshly and analyse your games? When do they start analysing your referrals?
