Back in 2014, a warning was added for posters who are on their way to receiving a question ban. That post includes screenshots of the warning, but the visual styling depicted in the screenshots is noticeably different than the current styling.
Recently, we've had a couple people complain about not seeing these warnings, including one who is quite adamant that they did not see a warning that looks like that.
Thus the question: has the warning's appearance changed since 2014? If so, what does it look like currently?
