Dear HN: Please stop messing up my userstyle

Every so often, it seems like someone decides to add an extra table row to the very top of the page.

The HTML here has few if any proper `class`es or `id`s, so my userstyle CSS must use `nth-child` instead. So when they add an extra row to the table, it throws off pretty much everything.

Can we stop this please? I don't know what `s.gif` is for but this is infuriating.
