[gentoo-user] [OT] Nigerian spam coming through google calendar invitations

[walt]

I thought I'd been rooted when I saw a notification pop up on my desktop
with no previous actions on my part -- it just appeared out of nowhere
for no apparent reason, offering to sell me gold dust (cheap!).

Turns out that evolution (a gnome clone of MS Outook) was checking my
google calendar account automatically and I didn't even know it.  I
use gmail every day, but never use the google calendar app that comes
bundled with the gmail account.

I do use the evolution calendar function on this local machine for
popup reminders of birthdays, etc, but never do I publish my calendar
on the internet.

So, be aware that some calendar apps are set to do this insane stuff
by default -- and google calendar accepts unsolicited invitations by
default(!).  Maybe you should turn that off if you're not expecting
a Nigerian offer you can't refuse?
