(Original thread title was "The ads on NSC are not just intrusive, they're obstructive")
Take a look at this screenshot. The ad cannot be moved or closed, so the only thing is to click on it. It takes you to its website, but even then there is no way to read the post....apart from logging in, of course. And most visitors to this site don't do that. So, are we trying to drive non-members away?
