This has already been confirmed as no.
If you get a new subscription, do you suddenly gain access to all of the old articles?
If someone hacks your account and both of you are online at the same time, will WotC kill your account and force you to talk to someone on a 1-800 # while you hunt around your PC or notes for your approval code?
No idea on these, but if your accounts get hacked that often to be a concern, I'd suggest coming up with new passwords and getting a spyware scanner.
