They give you the choice of the regular Donkey with the small ad banner and the cydoor version. I have the regular one.
Cydoor
2.18.02 -There are now two versions of the latest Windows client on the download page. One serves the banners using the Cydoor ad-network. I know they have gotten a lot of bad press and accusations of being spyware, but as far as I can tell they aren't. They collect no personal information all they do is serve up the banner at the top of the donkey. If anyone determines that this is not true please let us know and we will remove them immediately.
The reason we choose to use them is that we are making virtually no money from our previous banner system. Anyway we left the non-cydoor version up there for those of you that are really bothered by them. But if you are not please use the Cydoor version.
