This is interesting to me. Is it a problem with the Adwords/doubleclick API, or just some adblock checker hack from bloomberg's side?
I don't know. The nag's styling and language matched Bloomberg's, if that's any clue. It had a stern warning of some kind, and the only way to continue was to press a button in the alert, which I refused to do out of principle.
I refreshed a couple times and it didn't happen again.
The article was quite low on substance, but quite readable for me. With no ads at all. And no ad blocker nag.
