A couple days ago, when browsing through my Newsblur, I was being spontaneously redirected to a dodgy site. Looking into it, it seems the RSS is loading an iFrame which is triggering a URL load for the parent browser with a bunch of my meta data in the URL params.
Turns out, I added the Techcrunch RSS by putting the plain website into the ‘Add a new site’ and choosing an autocomplete option. I don’t know if it’s changed since, but the feed URL for it in my Newsblur is now (DO NOT CLICK) TechCrunch (DO NOT CLICK).
I have a screen recording of the recreation which I can give to you privately, Samuel, if you want it.
