@salbahis provided the best answers on @TS query. First off, the blog is hosted on blogger. If you read Blogger's TOS, they will not remove the content nor remove/delete a blog even if it involves
personal attacks or alleged defamation unless provided with a court order. At present, our country has no explicit legislation on cyber bullying or Internet libel. Even the first libel case (Belo v. Guevarra) in Facebook gets junked by the court as there is no such crime as Internet libel here in the Philippines.
@TS, I'm just curious how did you know about the blog? Do you personally know who owns it? I may never know a blog writes up bad at me if the blog itself has no or even less readers. If it has been shared to many people then you may start worrying.
