This service allows a legitimate user to observe the last 5
of which users logged in to the account, this is known as the
account activity' feature.

Uh, so what?

Most remote-login systems allow you to do that.

While this service is helpful to know if your account has been
accessed by intruders, it also allows the intruder to get the IP
addresses of legitimate users of the account.

With this IP address they can get clues about the authorised
account holder.

If someone gets access to my email, the last thing I am worried
about them getting is my IP address. My email account has much more
sensitive and revealing information that would be useful to an

If I work in a sensitive government job, the intruder can know
using this feature.

If you work in a sensitive environment and are connecting to a
webmail provider then that alone is a problem.

If I have been in an area, place in the world which may
or tip a spouse off about a relationship cheat, this will show up
locations of which the authoritised users have been.

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
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
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

Please, leave the real research to the experts and stop trying to
whore attention.
