Okay, i learned a new method to getting passwords for servers which i am going to share with you today.
Step 1: Open your blockland game and look for a server (make sure the server is passworded)
Step 2: Put in the password if the person is your friend and they gave it to you..
Now, if you do not know the password to the server, heres what to do next.
Step 3: Give up and join a non-passworded server.
I hope this helped :))
