How about not using adblock on HWC so you can actually give back to a site that provides you with a forum and so much more? You do realize that through those ads we are able to pay for site upkeep, keep the servers running, etc. right? And if you know that already, why the hell would you not add HWC to your list of exceptions?
As for the "Congrats!" thing, we don't have it so it may have been from another tab. If it happened to pop up our usual Google banner rotation, consider it nuked immediately.
