Yes, they get paid with upvotes and not views, but spreading your word out on other platforms—if your content is not recognized in Steemit—is one way to garner upvotes too, so the incentivized posting is still there. Posts that redirect to Steemit don't have any significance on this forum except that they just add up to the clutter and noise this forum already has.
Breaking one of the (unofficial) rules asks for one's ban. It's an incetivized post, though being indirect. A ban of 7 days for the first offense should be implemented since it's spam no matter how you look at it. Also, reporting 2 posts under 3 minutes is a new record for me.
