M’s identity

Just read a sister’s comment on a blog post that contains M’s name. She requested the poster to delete the M’s surname etc. As well as the word M itself! I was thinking whether it’s actually necessary to do so, I mean the organisation is not like FBI or ASIO or something.. and the Ms are not exactly spies.. unless they’re coming to countries saying want to do a job but actually doing something else.
argh, why even blogging need to be restriced, confined and censored!
update: after some thinking, yea maybe for sensitive issues like ppl’s identity (and security), some discretion is needed, i don’t mind a bit of censorship over this issue.
