no need to be scared...fact is, you 'can' be 98% anonymous if you are willing to work hard at it, but it is usually WAY too much trouble for the average person, just as it usually too much trouble for someone to 'identify' you, if you don't want to be known... except as just a set of numbers. The CIA has its special techniques, but I think that usually involves getting a court order for records from an ISP.

The point is, there's a big difference between being able to identify you well enough to drive to your door, and being able to block certain sets of numbers from access to your site.

Just be nice, and no one will have any reason to do either.
