Updated rules on free links, asking for links, scripters preventing sharing of free links

this change is exactly because there was so much ambiguity with #paid-media

So there are 3 categories that new posts could fall under

  1. free link included by the scripter
  2. free link not included by the scripter, but they don’t mind if someone else shares it in the replies
  3. free link not included by the scripter, and they don’t want anyone to share a free link

The problem is that tagging based on (2) becomes invalid once anyone shares a link in the replies. So the new rules around no-free-links only targets case (3)
