Yes, it does seem to still be there. I switched my user-agent to the Opera Mobile one and then reloaded the forum index, and the ad seems to still be there. I don't think it's a cached copy - I reloaded a few times, and my notifications seem up-to-date there.
I'm using Firefox for what it's worth, but I can reproduce most of the Opera issues if I use its user agent. Just for testing reasons, you understand.
