I asked the crawl/indexing team about this, and it looks like sana.sy hasn't let Google crawl the site since August. It's unclear whether it's deliberate vs. something like timeouts. So it's nothing on Google's side. No webspam-related issues or anything like that, either. In fact, if sana.sy were to register for Google's free webmaster console at google.com/webmasters/ , then they would have gotten automatic alert emails regarding the high level of errors we get when trying to crawl the site.
