The spammer is using several unique words which identify him as a free advertiser or search engine exploiter. Word's like fortune teller and casting spells, for example. These suspicious words should cause the spam attempt to fail and the sneaky user to be suspended.

Also note that those overseeing this international UNA site may be asleep while the spamming occurs. Therefore it goes on for hours before detected.

As others have stated already: No new user needs to start multiple discussion topics in one day.
