According to Wikipedia, In computing and specifically Internet, a leech or leecher is one who benefits, usually deliberately, from others’ information or effort but does not offer anything in return, or makes only token offerings in an attempt to avoid being called a leech. In economics this type of behavior is called “free riding” and is associated with the free rider problem.
Now a day, the Leech server that I’m use is: Vinaleech.com.
