So finally received a note from the happiness engineers:
Key words: free site (so you get what you pay for)
sometimes place ads – (yes, four of them, every post)
Ads determined by location, browsing history (to be clear, I have never looked up foot fungus, swollen legs, stretchy underwear, or life insurance, to name a few)
Paid plans (no ads)
Upgrade your site (you know you want to) uh huh. . .
