Rohit Mahajan tweeted tonight that this was one of the images deleted from Weibo on June 4th. It's an amazing photo, though apparently not amazing enough to elude interpretation.
If I'm reading this correctly, it also seems that the weibo user, with the name Freedom Abib/barkcheekhandle is posting from the US, not from within China. FWIW. morning after update: and now the account, which I'd seen via the tw.weibo.com site, has been deleted.
