- rootusrootus 5y agoAt a certain point -- probably the moment it becomes a business unto itself -- this kind of data collection should be subject to all the same rules we've come up with for credit bureaus. It should be a legal requirement that I can get the entire profile they have built for me.
- nerdponx 5y agoI was wondering specifically if they have special cases to identify such "personal" email domains and use them for record linkage. It seems like an obvious thing to try, but maybe not worth the effort of implementing it, given the high risk of false positives and the low % of people who actually do stuff like this (not to mention they're probably not people who click on ads anyway).
