'Promoted' posts now appear on the front page, repeatedly.

I don't think there's a way to get them without using the 'has' functionality...

Mystified by the response below, I tried a clean minimal install and discovered imgur only serves these advertised posts to users who are logged in! Unexpected, certainly, but doesn't solve the problem.
I can not reproduce what OP sees in firefox or chrome
Logon required?
I have an account but I get no such promoted stuff
