Injustice in League

Be careful of playing games at your friend's house. I travel a lot and Riot has punished me for using my account different places while i travel. Apparently all the different IP addresses confuse them and they thought I was being boosted. Instead of them proving it, they dismissed my concern for it and replied with "We have already explained the context of your suspension. We will not be removing the punishment and consider this matter closed." I would be very cautious because it doesn't seem like they have a real system to this as i was also told "people look very closely at the account" which leads me to believe that there is no real system in place just some guy behind a desk randomly picking people. By mostly looking at IP addresses and your win rate. Just a fair warning to everyone that you should be on the defense.
