Websites can't see your mac, only the mac of the nearest router, which
is not enough to identify the visitor even on small site.

Flash cookies was a very common practice some time ago, though.

   Ok then. Maybe they block the mac of the nearest router. At the time it
   happened to me (4-5 years ago) I was always working over the same
   wireless connection. Also, Computer 'names' are transmitted. One can
   see that on IRC. I broke out of an email relay's black hole once by
   changing my computer name (windows, a decade ago). Flash cookies are
   still quite common even with the advent of cleaners that remove them.
   Hidden ones might be harder to find unless you physically go searching
   for them.
