Which summoned have troll records?

Considering Riot actively discourages such sites (doesn't let them use the API, doesn't let comments like that on the boards, etc), I don't think you'll find the URL you're looking for here.

Worth pointing out it would all be a bunch of hear-say. You'll end up tainting your opinion of a teammate based on the word of someone you don't know who could just be bias because they had one bad game with the person.

Url* summoners*

I could never forget about urf <3 lol

(ps thanks for the correction post. I had no idea what you were talking about lol)
