It's insane to me that it's not "common knowledge" to AT LEAST hash the passwords. It's also interesting because 6 used an encryption algorithm, 10 used MD5 which is as good as plaintext nowadays IMO, and 8 used Base64, so even though 24 people thought they "secured it" the passwords are trivial to recover.
To play devil’s advocate, to me plaintext means I want to finish quickly because you haven’t asked and are paying too little, while any solution other than bcrypt/pbkdf2 means I don’t know what I’m doing.
Some sources now recommend argon2 over those two, could that be another right answer?
