Sometimes when one is just starting out, ANYTHING to get a hit can be useful. For example, I recently started what could quite possibly be the most important Blog ever written in the history of the World (wide web). So, if I get a hit from "Jesuslovessatan", and that person uses her blackmagic to direct more traffic to my site, well, by golly, isn't that a good thing?
These guys are trying to generate traffic. And there is an option to turn it off. So it should make everybody happy. Maybe they should have "advertised" the option and given people the option to turn it on instead of it being on by default, but its not like they came storming into the house in the middle of the night to drag you away for expressing your opinions.
Can't we all just get along?
