Thanks to Doc and DHC for pointing this out!
The banner network that serves these banners introduced expandable banners and even a new "floating" size without letting us know. The new floating format (yuck!
) now won't apear anymore at all, as for the expandable ones, I removed cheap tickets, but unfortunately there is no way to automatically weed out this type of ad for the future. I've already sent a complaint mail to the banner company, and if they don't make it possible we might eventually leave them all together. In the meantime, if you encounter another one of those, please let me know and I'll put my exterminator boots on.
Again, apart from the static ads on the page we only intend to serve one popunder (appearing UNDER the page and not ON it) per visit. If you get anything else (except for the AOL bug I mentioned above) please DO complain - it's really not intended.
