Some proponents of targeted advertising claim that there is no harm in companies selling user data as long as most personal information like names, ages, and zip codes are removed.
Why is this argument inaccurate?
Even a little bit of data, like what kind of products they buy, can be enough to identify the users.
It is impossible to remove most personal information from user data.
Collecting and selling data on users is illegal.
None of these; this argument is valid.
