I accidentally ended up at a job in the ad-serving business for two years and this is so accurate. (Who knew "analytics" really meant "ad conversions"?) If there are entire product lines dedicated to blocking the thing you do, it's very demoralizing.
No, it's very demoralizing to find that what you are doing for a living (that isn't what you expected to be doing) is so disgusting to other people that there are commercial tools devoted to blocking you.
