I would doubt that. They have to be typing these themselves with some kind of system. I'm sure your right about whatever where it's located but these messages must be coming from staff.
I have administered a number of systems ("staff" as it were) and I was not given access to change the GUI in some of them. I would have to tell my programmers (who were based in India) what I wanted to add. Quite a few times there were spelling or grammar errors in the system that I had to have corrected. It depends on how much latitude IT gives the system support people.
