Ameritrade leaking email addresses?

Could I dare speculate that it is AT&T that has the leaky
employee? After all, they are engaged by BigBrother to spy on all
internet traffic, ostensibily to catch Ossama and friends and
other nere do wells. So, I suppose that an unscrupulous AT&T jerk
is as good a candidate as any to attribute the leakage.

Also, given that the NSA is likely to be able to crack even AES256
at this point and that your traffic needs to be in plaintext for
BigBrother to use it, I can also easily imagine that the plaintext
is readily visible at the AT&T evesdropping points.

Just my speculation, of course.
