Devs recent answer ^^
It seems to be someone pretending to be the devs while claiming it's from a "reliable source". I wouldn't really trust anyone from the comments, the devs try to minimize their existence for obvious reasons. They don't even have any known mangago accounts, so I would take everything with a grain of salt unless you get a response directly from their email. Just hope we get them back within a few weeks. If not I'm probably gonna give up and try hunting down what I was reading before.

If I understand correctly, I will never get back my 'already read' list since I hadn't noted my readings, but what about the 'currently reading' and 'want to read' lists? Are they lost too? Is there a chance to get them back?
