From what i see in this forum is that they keep using wrong terms to define people who use hacks and claim it as their own.
I would rather call them Fakers/Posers.
Being a leech or leecher refers to the practice of benefiting, usually deliberately, from others' information or effort but not offering anything in return, or only token offerings in an attempt to avoid being called a leech.
-Wiki
A perfect example of leechers are the Script Kiddies
Or the ones who uses/practices hacking techniques poster by the Hacker.
I would also call myself a leecher because i use the "Techniques/Hacks" without giving something in return.
Imagine a Leech(Bloodsucking Parasite).
A Hacker is someone who creates/discovers "techniques" to bypass/abuse/exploit a certain program.
Script Kiddies are the one who uses hacks that are discovered by a Hacker.
