Question: without testing, how do you know that an automated "accessible system... its only going to make a landlords life worse" ?

Have you evidence this is true? I work with web hosting and clients can send support tickets at any time, but rarely do. They have the option of asking infinite questions such as, I made a change why did my website break, why is my site not in google for [insert impossible keyword here], I want to change the background color, why is the email from my mom spam... but it almost never happens.
