I think this is a very good point. A recommendation to substitute a

me a good balance between privacy and security. I agree that if
keeping your geolocation is a matter of life and death, you shouldn't
use email, but for me that is not a reason for the IP address to be
visible for anyone who can read the email. I think privacy matters,
even when it's not about life and death. Martijn.
I'm fascinated by the concern about geolocation.
How well does it work for other people? For me, it gives me the country
fairly reliably, and nothing else reliably at all.
A hashed IP address will not help issues with 'tracking' people using
their IP addresses (you just track people using the hashed address
instead). The only thing it will prevent is someone using geolocation,
which my tests suggest is pretty useless 99% of the time anyway...
