EmoteInfo provides user-level emote statistics based on traffic to https://www.destiny.gg/. Development for the chat at https://www.twitch.tv/xqc is currently in development.
Simply search a valid username (e.g. ze1ig, cake) for a user from https://www.destiny.gg/ into the search bar.
This site works because of https://overrustlelogs.net/ (ORL). Because of ORL and it's API, messages from each day since 2013 are available, and the info regarding emote usage is able to be gathered.
This project isn't currently setup for public contribution, but perhaps I will structure it for that in the future. It is currently open source because I want others to be able to see it easily, and I think it's also fun to show in this fashion.
