Just for example, I found this text on comingsoon.net here (http://www.comingsoon.net/films.php?id=50766),
In the second installment of Stephenie Meyer's phenomenally successful "Twilight" series, the romance between mortal and vampire soars to a new level as Bella Swan (Kristen Stewart) delves deeper into the mysteries of the supernatural world she yearns to become part of—only to find herself in greater peril than ever before.
Just Google it and you'll see there are Results 1 - 10 of about 2,780,000 just for this little piece of literature I got from there.
Now I don't know if people were copying from ComingSoon.Net or everybody copied from somewhere else or everybody else simply decided to get it from there. But now you know how many times same text floats over and over on the internet.
Isn't that spam? lol
