Recently, I have been trying to learn about PHP and using/storing passwords securely.
I came across this post: Exactly how do I use blowfish in PHP?
Which is marked as a duplicate of: best-way-to-use-php-to-encrypt-and-decrypt-passwords
But that post has been closed due to reasons of moderation. Shouldn't there be some kind of check in place to make sure this doesn't happen? Or at least, should the post Exactly how do I use blowfish in PHP? still be marked as a duplicate since the question is supposedly a duplicate of a question that no longer exists?
