I've read a lot of people recommending rackspace for adult traffic, why is this? My best guess is that networks like tj don't host the banners like pof and you need to self host them, is this correct?
I think the most recommended use for rackspace is CDN, your landing pages will be loaded faster from a CDN if you're doing international campaigns and your hosting is in US instead
Yeah it has nothing to do with your banners, because you upload them to their servers. Rackspace is generally used for CDN hosting like Dario said - to make your landers load faster.
You can't usually host a whole website on a CDN host. CDN is just for static files/pages. So mainly images, videos, etc. Generally a website includes JS and php and other dynamic properties.
So most ppl use both... a VPS to house the actual website php/html/etc. And a CDN host for .jpg's, .png's, .css's, videos, etc.
