Re: [Trisquel-users] On the NSA targeting readers of Linux Journal as "extremists"

[retro]

The ISP knows what address was assigned to a customer at a given time, at  
least as long as they keep the logs.

If commercial organisations can identify users using a combination of data  
then I'm sure a spy agency can, but such an agency is less likely to sell  
your data. In fact they probably keep it more securely than a multi-billion  
dollar business that can shrug off any fine.
