I am working on Toxicity website...
That shows a summoner's toxicity scale and lets you rate the summoner. Where existing sites like Lolking, Lolnexus, op.gg, etc, show you all the summoner's performance stats, my website will show you how they have been reviewed personally and how toxic they are (if at all). That way, you can go on and see...hmm this guy has a great k/d/a with his champion, but he has an 85% toxicity level. Better not get on him or attempt to give him advice, etc.
It will let you write written reviews on a summoner, rate his toxicity, share if you reported him and what you reported him (so you can see what he gets reported most for), etc.
(On a negative side, you can see your enemies toxicity level and see if there is a guy with high toxicity and use that to your advantage...like purposely try to tilt him ;) )
It has been in production for a while now and will be released as a beta soon. Thoughts?
