@diracdeltas @kjozwiak @iefremov @jumde , please check the PR

Methodology

• First I found out , the rewards related domains from : https://github.com/brave/brave-core/blob/9f2edc372ea22440dc382bfca758d3536dfbe022/build/commands/lib/whitelistedUrlPrefixes.js
• Modified "[brave_network_audit_browsertest.cc]" , to add a browsertest which starts the browser, navigates to twitter/github/youtube/reddit/etc. pages, and then fails if any rewards domains are found in the network log.
