If that fails, you can also contact me - my account is Taiwan-registered and still has full access. I can save your references, photos, and friends list, but not your private messages.
As mentioned in https://news.ycombinator.com/item?id=23219760 references is coming.
The verification issue though for import is a big one, we couldn't just trust a JSON file the user has uploaded to have real references, there would be nothing stopping them writing their own glowing references.
Verification wouldn't be trivial, but a Trusted Human, could check that both their CS and their import match, at a glance - or the public profile could be extracted to partially automate the process.
