A self-proclaimed data enthusiast calling themselves ‘ThinkingOne’ has made a huge database containing 201 million pieces of user data from X freely available. The data is said to have come from two previous leaks and includes email addresses, locations and profile data of users of the social media platform.
wouldn’t profilers simply track via the domain tld instead of the whole address…shopping1 at uniquedomain, bank2 at uniquedomain , etc
and in the case of aliasing, couldnt a domain provider tell where the aliases rout to and sell that info as a side earner?
Great questions! Seriously, those made me think for sure.
For question one, I suppose a profiler could do that. If my domain name is myemaildomain.com, they probably could track all emails and sell it collectively. But I don’t think corporations do that at this time. That would be akin to profiling all Hotmail, Gmail, Live, etc emails, appreciating those are massive services. I suppose if nefarious actors were to do that to my domain, I could consider switching domains - I have multiple domain names I own, and it’d be trivial to use the other ones. In the years I’ve been using a custom domain for email, I haven’t encountered any nefarious actors and have significantly eliminated any spam.
For question two, the domain provider I use doesn’t do that in their terms of service. However, if they did look at my MX records and decided they wanted to profile me as a user of Addy, they definitely could do that. Though it would hurt their business as many users would migrate their domains to new registrars - I certainly would move my domains to a new registrar!
