Practically every popular storage service (and by popular, I mean Facebook, Google +, Flickr) has a history of deleting legitimate accounts without explanation.
Now, I keep any photos I want backed up in several other places, but I often use those service (FB especially) for my crappy photos of groups of friends at parties or whatever. Fun memories, but poor photos.
I am beginning to hear more and more horror stories.
And I got a fright today because last week, they shut down the “Light Stalking” G+ account cos it wasn’t a “real name”, but apparently I got off lightly because I still have my email, docs, picassa etc for that account. Some people lost the whole lot!!
