I do get targeted ads, it's called newletters I sign up for on services, and blogs of techincal companies I keep up with. Both work well for things I am interested in.

As yourself this: How do you feel about the possibility of any personal information you give to any company may be given to others without your consent (or "with your consent" behind a huge wall of "this is how we use your data, take it or leave it"), and for those companies to sell it to data arrgrators to build a complete picture of you, to sell it to anyone with enough cash?

I am fine with pseudo-anonymous ad targeting. You can collect personal "interests" without collecting truly identifying PII.

However, what you describe already happens and has for decades, in the offline world. Tons of personal info, like real estate and voter records, are already public in many jurisdictions anyway. Insurance companies, credit card companies, phone companies, and everyone else all take this stuff and spam the hell out of everyone.
