[Meta] New Automod Rule - Minimum Comment Karma before Submissions

After feedback from many members and discussions within the mod team, we have decided to implement a new Automod rule:

**Rule:** Effective immediately, **users must have at least 10 comment karma** **within** r/datascience **before they can make a top-level submission.**

The desired outcomes are:

1. Reduce pure self-promotion botspam
2. Reduce the number of top-level submissions that belong to the Weekly Sticky thread.

**Please let us know if it appears to be working incorrectly or causing unwanted side effects.**
