The admins to perform upgrades, monitoring, fixes, etc… will require root access to the database. That means they can alter all your posts to say *blah blah blah" if they wanted.
Similarly passwords will be encrypted within the database and encryption algorithms have to be able to go in both directions. Normally they need a seed value to start random generation. The admin defines the seed as a result an admin can decrypt everything in the database.
This is incorrect, passwords should be hashed, not encrypted. Hashing is only one way (unless you use a terrible hashing algorithm or your attackers have access to a quantum computer), these hashes are also often salted, which means adding extra data to the hash to protect against some attacks
