Looks like this issue is finally "fixed" in Ubuntu 17.10 where the guest session is no longer available.

Status in lightdm package in Ubuntu: Triaged Status in unity-control-center package in Ubuntu: Triaged Bug description: "Guest Access" should be disabled by default. It is an unexpected "feature", on an otherwise secure system. Until a GUI option is added (https://bugs.launchpad.net/ubuntu/+source/gnome-control- center/+bug/886415), it is also an un-intuitive feature to disable. I've found it only invites trouble. For me, trouble had the face of my children while I was at work. =) They found that they were able to use my laptop, without logging in. Then on their PC they found that, while logged into their account, using the "Guest Access" bypassed the proxy settings setup in their Firefox profile. Please consider defaulting both pre-logon and post-logon Guest Access to off.
