Just a quick one: I am taking down all iframe widgets effective immediately. I reluctantly posted a few from very carefully vetted individuals whom I consider friends, All of a sudden this morning I find the site is displaying popups. I don’t have time to test each widget in isolation, so they are all gone. That is the most likely cause of the poop-ups. The next possibility is I’ve been hacked. I recently put up a conservative version of an open source project on this server for a friend for testing. Maybe it wasn’t a good idea.
