What exactly happened to this, anyway? I've got all the adblocking junk on my PC switched off right now, but I don't see any Google Adsense presence.

Come to think of it, you're right. My best guess is the account was suspended for either violating some terms of service, or had fraudulent clicks :p

I thought it was weird how, just today, whenever browsing Gamingforce I was having to press the back button twice to get to the previous page I was at. So I rolled over the back button after following a link, and a http://pagead2.googlesyndication.com URL shows up.

Heh: Doubleback

Although upon looking at this thread, I do see somewhat of an explanation. I never noticed that Google ads were to be implemented. They never even appeared on my thing anyway.

They came and went. We're not really sure why they went.
