This is what has worked for me, it will increase your netflix account from a few days to a few months. Go to the account settings, set the "communication preferences" to none, no text, no email, whenever an account change is made. Write down the password, change the password but unclick the options that kicks everyone out, says something like "make everyone sign in again". So, all that did was change the password and the owners never found out. Now every other leecher that tries to log in to the netflix account, wont be able to, and move on to the next account. After a month or two, change the password back to the original, so that the owners will still have access to their account and change the payment and stuff.
