Personally I agree with the sentiment. I believe they put up the banners, and more codes will resurface over the time from sources other then the site we all are currently refreshing.

Now I would like to put in some technical data for all of us:
Guys - What time of the did you hit the page succesfuly getting a code ?
To me It happened around 6-7 AM UTC +1 (Belehrad, Bratislava, Budapest, etc) time zone, the codes were already there.
If we can figure out if they upload the codes at set times then its better then randomly hitting the refresh button (especially for people like moi, who have to work during the day)
