This website has more moving ads than any I've ever seen. Every add is moving and have graphics just as detailed as the games on here. The ones that are particularly annoying are the ones that popup when you pass a mouse pointer over them.
They drastically slow down games (on my old 2.0 single core) and make it much easier to exploit them. Amophus Plus, for example, is not meant to be played at 8 FPS.
Most other websites seem to get by without the in-your-face, moving ads. Can we go back to the way things were 2-3 weeks ago?
