I personally have a long list of products not to buy. If you somehow repeat the same ad and I remember your product, I stop buying said product. If youre wasting your money on spamming ads, your product sure as shit isnt better than competitors', since they waste less on ads, more on product. I dont use ad blockers, they make it harder for me to find out who has the poorer product.

Wow, that sounds like a ton of work. I think a better idea is to use an ad-blocker, but run a program in the background that downloads the ads (or maybe just samples them, to save bandwidth and resources), processes them to find brand names, and then stores these brand names in a database so you can find their relative frequency and assign a score to each. Then you can just query the db when you want to buy something to find that brand's acceptability score.
