Their sites completely
stopped working over half a year ago. Their sites only returned random content.
When their sites came back last month I noticed that they now have NATS. Their old links had a Webmaster-ID in their URL, but their new links are "standard NATS" links. They obviously managed to import my login data to their new NATS backend. I have no idea why they didn't manage to rewrite links to still work. That should have been a simple thing to do, but I guess that's just how Media Revenue rolls...
Didn't bother to investigate more since most of the (new) links I was able to get in their NATS backend return white pages or "site not found" messages.
