No, nobody is deliberately pushing that topic to the top to annoy you.
As a clarification, this is a normal topic. It doesn’t have any special attributes — and will not disappear after you have posted something in it or have left a review on TrustPilot.
Unless of course you make it disappear, just like a real plane, it will not do what you think about until you press the correct buttons to make it do so.
