In the old days, we used to call those [[!wikipedia web bugs]]. Nowadays, they seem so pervasive that we don't even notice. Nevertheless, I think it would be important to remove those snitches from the ikiwiki home page.
A simple fix would be to ship those icons with ikiwiki and serve them locally, but there may be legal issues with redistributing those icons in the source code... Would it be covered by fair use? The [upstream library](https://code.google.com/p/openid-selector/) doesn't actually exhibit that problem, and ships those icons directly as a [PNG sprite](https://code.google.com/p/openid-selector/source/browse/#svn%2Ftrunk%2Fimages). -- [[anarcat]]
