My old myspace had several links to my clients. Yesterday I added a few more links and now all my links have the msplinks redirect. Moral of the story: If you have an older profile - don't go back and edit it. All of your links will be updated to the new redirect.
Thanks for sharing seans9! Unfortunately the same already happened to me, but at least I know what's going on then!
MySpace has a lot of kids on it. And kids are strange creatures They tend to copy each other and send out viral content. So, if your site is a good fit for a young audience you would certainly get a lot of traffic from that.
