LoLnexus in the past let me know that. I don't use that kind of stuff as I don't care about what things opponents use or what rank they are. It's just you stumble on these things in 4 years of LoL gaming. But as recently I had bad experience with premades this would be useful.
I wouldnt waste time trying to talk to them. Its good info in lane aswell as premades will camp each others lanes most likely.
I couldn't find anything myself. And I don't get why anyone could just go to internet and see every small detail in my account even what names my pet's have. But I can't see who is premade.
