Summary: * Simplified `Url` to only keep track of what we need (we can change back later) * Normalize domain: remove subdomains like `www`, `www2` and lower case * Return the full domain in the JSON value field * Updated offensive url example Reviewed By: JonCoens Differential Revision: D4705403 fbshipit-source-id: e5d11ee
