"Guarantee" is a strong word, wouldn't you say? Simple case: you have
two messages; one you know I wrote, the other I didn't, you don't know
which.  You could say that is "anonymity".  That's a reasonable use 
of the term.  But it wouldn't make me feel secure.  So that boils 
down to what is a "large" number.  (I confess I *haven't* read the 
archives about flooding attacks.  However, I don't see how they could 
be guarded against if *all* the other remailers are in collusion.  
But perhaps that case has been considered...)

Of course.  I don't know Raph from Adam -- *I* just see a list posted
on cypherpunks.  For that matter, of course, you could be Tim May, as
are all the "(T)ruth (M)ongers", and many other of the "personalities"
on this list...

J E Hoover certified them?  If I persist in my conspiracy theory, 
then it makes absolutely no difference how they qualify -- the list 
is just text produced by the cp conspiracy, after all, creatively 
edited to make it look legit.

But seriously, I thought it was buy sending "ping" messages through 
them -- is there something more to it?

How do you know that?  And why should I believe you?

Anyway, Ulf, as I said in my previous message, this was all started by
me poking fun of my "contemptible" status among the cyphperpunks. 
That status is partially fueled by the fact that I work for that evil
conspiracy, the "government".  (In all honesty, I must confess that it
may also be partially fueled by various failings of my own.)
