@NoRaAintAllBad, to answer your question, yes you can mute a member. Click on their name until you get to their profile page, then:
I think it’s also interesting that you can see the person’s activity, such as people that have liked that members posts the most, or members that they have liked the most. I’d expect active participants of months to have relatively high numbers. This particular person (not being named) doesn’t seem to be much of a participant in regards to giving props. The most likes any member has gotten from this other member is 3 likes, total. 
To be crystal clear, the stats and profile I’m referencing are NOT @Francisco or @scotchman. They just happen to have garnered the most likes by the member in question.
