Looks like this may be my own fault for running noscript and blocking most ads; I may be getting whatever the default content of the ad box is, or whatever’s left over from last time I let the scripts run.
Allowing some of the scripts to run once (well, allowing all, though the refresh promptly came up with a whole bunch of other foreign scripts that it blocked) made the particularly annoying ad go away.
I know, “don’t run noscript, you’re blocking our income stream.” I didn’t run ad blockers until annoying roll-over popups and gratuitous animations/noises became intolerable. I could make an exception for BB, for a while at least, and see whether the online advertising industry has learned not to be too annoying to be tolerated… but I really hate opening up more permissions than are required to run the site; it’s a potential security issue as well as an annoyance factor.
