Account sharing is against the rules, but...
...does Riot actually enforce it? I'm just wondering, do they actually monitor IP changes, or does it go off of reports? I was watching this video and I started thinking about it, and I was curious as to how that works, because how do they tell if someone is account sharing? What if someone simply logs in from a different location and plays their account? Or what if someone uses a VPN/Proxy and their IP changes?
