On one had, yeah... she shouldn't have to deal with it because the statements are allegedly false; on the other hand, if it were true he would technically have every right to share it.
Well it exists and the latest report from New Zealand based Netsafe, states it is a NZ $444 Million problem. So what is the societal effects globally or by country. If New Zealand has a population of 4 Million people, potentially it could be far higher than the cost of compliance per annum.
