OK, just FYI, I cleared my cache and cookies and still seeing ads.

When I cleared everything and went to the main gamedev home page, I had no ads, and when I when into this post to reply, ads appeared (3 of them).

I dunno if that helps or not. But at this point I'd say it's a server side thing.
 

See PM.
