It'll give you the country, possibly the state, that is about it. You'd need a court order to get any more information and good luck with that. <more boring, baseless claims> > >In short, this feature is useless, and there is no work around for >legitmate account holders to withhold their IP address from the >'Last >account activity' feature. Useless? I value knowing if someone else is accessing my email account via that feature, much more than I worry about someone finding my IP address. > >Time to scrap this feature, its full of social flaws, which is >only >empowering bad guys. No, not time to "scrap this feature". This is another sad attempt at attention whoring, but you'll find that more people care about the risks of NOT having this feature than they care about the fact someone could find the IP address you connected to, which in this day and age is trivially available information. Please, leave the real research to the experts and stop trying to whore attention. -----BEGIN PGP SIGNATURE----- Charset: UTF8 Version: Hush 3.0 Note: This signature can be verified at https://www.hushtools.com/verify wpwEAQMCAAYFAkjVNJIACgkQGwcl4JwqQeBlgwP+KaNbh8Su5fsYzqD8LNfqemQZGlIT N/vQLgXfWeGia7HqLVpWYzSG4ZYdU5+rRq6oBtnBlnriNjUFXNOda4nNXXJiGKpVCZj+ QLXti/uDN8GuDQvKxucjrwdaQrmkdpzBWnhBcfqRq6LMkMu+ZYEwsWLI+BMbwXAIcF1s fsMKh4Y= =AEbA -----END PGP SIGNATURE----- _______________________________________________ Full-Disclosure - We believe in it.
