Not a complaint, but just a general comment about ads:
You can't stop the ads on this site, but you can influence their content. Last week I decided to try a new brand of golf balls. So I googled "srixon Q-start yellow sale" (not in quotes). I got a decent price and bought a couple dozen. So then for the next several days about half my ads on HB were for golf balls! I'd rather see ProV1X ads than ads for some random s#!t I'm not interested in.
Last week a friend asked me whether I though a used Flightscope is a good deal (golf ball flight sensor). So I googled that. This morning all seven ads on the front page of HB were for different golf related products.
Summary: You can't stop the ads, but you can at least influence their content by making a few directed google searches. Using the word "sale" in the search seems to increase the influence of that search. The searches I make daily for my job never result in related ads (I think) because I'm not looking to buy something or compare prices (and don't use the word "sale" in the work searches).
So there's that.
