Inevitably these sorts of infringements would always come down to "define professional". A jury of our peers would all feel very differently about whom exactly that SJW boot should stomp in any given case.Mods need to grow a pair.
This is an example of what's holding IndieTalk back. An amateur asking for professional advice and gets abusive when s/he doesn't like the response. Failure to stomp this behavior will encourage the fools to cause a further exodus of experience elsewhere.
