Ads are not accurately placed in categories.
I receive mostly ads about crypto, which I am not interested in at all. I always downvote them, and when I view the category to opt out of it, I see completely unrelated category titles.
For instance, you would expect to see crypto categorized as “personal finance,” but my history shows crypto ads in categories such as:
Food & Drink
Technology & Computing (this is closer, but still a stretch)
Furthermore, when I opt out of a category, I receive the message that I will “no longer receive ads from this category,” but I still do.
In my picture, you can see that I am opted out of personal finance as of July 2, yet I continue to receive ads in this category:
I would be willing to complete a survey to call-out my interests, and have done multiple survey monkey surveys that I assumed would do just that, but I still receive crypto ads 10:1 over any other ad.
I just received my first “Defi” category ad this morning, and opted out. the second ad I received after opting out was “Defi” again.
