"This is called libel or slander, and this is 
against the law."

actually, you're incorrect; libel is a FALSE 
publication that damages a person's reputation, 
whereas what she has posted is to be assumed to 
be true.  and while libel is written, slander is 
spoken, and since you can't hear the person who 
posted, this couldn't possibly be considered 
slander.

so no, the posting of the previous information, 
whether you agree with it's publicity or not, is 
not against the law.  it's the same as my 
favorite chinese restaurant, which posts checks 
that have bounced on it's bulletin board beside 
the register, not covering the name or address of 
the person who has written it; while i might not 
agree with this practice, i see it's purpose and 
possible usefulness, and most importantly, it's 
legality.
