OP you are way too overthinking it. You're drawing correlation when there is none. From your other posts, it sounds like you fly a bit but definitely not in the "intense" category of many on here.

Bear in mind, many of us fly CX multiple times a week. Inevitably sometimes we have bad experiences or are in bad moods. And YES Cathay does track passengers (aka your question at the end isn't comprehensivr), but you would have to be flying way way way way more than you do or acting FAR worse to get noticed.
