BOTS IN ARAM!!

So I just jammed a game of aram only to find I was placed with bots, these bots had normal usernames but behaved very differently, they would group up under our tower and just move around. There were 3 on my team and 4 on the other, I was playing nunu and person on my team was Ashe and enemy player was nocturne, we all had a discussion and felt it was really weird, I feel like these are fake computer programmed players who are trying to farm wins quickly, I tried to friend all of the players but they would not accept nor talk.

Could someone please explain (BTW we won) 😂 ~6 Stacks
