You would think this, but as a counter example Xbox (back in the 360 days) had a "report gamertag as offensive" (aka offensive username).

Users could pay $ to change their gamertag (~$10).

It was fairly common to see people publically asking "please report my name as offensive" as it was known that if you got enough reports, you would be "forced" to change your name for free. People who wanted to change their name anyway would solicit reports against themselves to avoid a $10 fee.

Clearly no human was reviewing these reports... and that was a paid service!
