This account was banned from contacting support (almost two years ago) due to ongoing use of extremely offensive and derogatory language in a hostile manner towards our support agents (including homophobic slurs).
We always warn players multiple times before we resort to banning the player from contacting support. Additionally I want to point out that you really have to be extremely nasty to get banned from support, so don't worry if you happen to express yourself with a couple of expletives mixed in, when contacting us.
I agree that the way it's displayed here, without any context, makes it look very out of place and even rude.
Thanks for the feedback! We'll look into improving the text and automation.
