I can't speak to outside the EU, but if you're in it, they've enacted a law requiring total data erasure, no questions asked, at the concerned's request. To be able, or at even to admit to being able, to recover data from that point would be a huge illegal violation of personal privacy. Some companies enact delays on this, I don't know the legal details, but I can say, that in spite of what they say about when it's on the internet it's there, deletions carried out under these operating procedures will come as close to complete erasure as is currently technologically possible.
