For the record, EVERYTHING I put in writing I do so with the assumption that the one person in the world who hates me and would hurt me any way they can will be able to get to it.
Everything.
I don’t care all that much about internet security.
That's a good start.
But there's more to worry about than just that.
Scenario 1: Someone gains access to your email and posts it. You've got that covered.
Scenario 2: Someone gains access to your email and deletes all or some of it. ???
Scenario 3: Someone gains access to your email modifies the stored messages. ???
Scenario 4: Someone gains access to your email and sends out email, purporting to be you, in a manner that is unflattering. Say, adding your name to a bestiality mailing list. While CCing your mother. "Yes, I'd like to receive daily pictures of people having sex with goats! Thanks, RobRoy." ???
I don’t care all that much about internet security.
That's not surprising. A lot of people don't care about physical security until they've been robbed or mugged. You just haven't been mugged yet.
