I wasn't even talking about banning or blocking me.  I was, as you'll see
in my other response, exercising the end-to-end architecture of the 
Internet, as members of this list regularly exhort that I should be able
to.

"This is why we can't have nice things" is not, actually, a sufficiently
useful excuse for me to not agree with that principle.
