They call themselves hackers (which is not the same as a cracker, a hacker is a programmer, a cracker is a person who breaks into computers), while they are neither hackers or crackers.
They use other peoples programs to do their simple "hacking", and usually end up getting caught.
Hackers are really cool people. Script kiddies are morons.
Cracker: I just broke into the CIA's webpage and replaced all occurances of the president's name with "Mr. Dumbass", It's funny as hell!
Script Kiddie: j0, ph00! I ju57 stolezored me a b0rkified wind0ze 3.1 b0xor. It r0x0rz my s0x0rz. I wundr if it g0tz Linux on it? Whutz Linux anywayz?
These people need a good slap, and give professional crackers and programmers a bad name.
Despite what you may hear, good crackers don't often get caught. The people that get caught are dipshit n00bs who don't know enough about what they are doing to cover their tracks.
These people make me sick.
In general, the average script kiddie is aged 12-?? as anyone with a computer and the desire to become a hacker is capable of becoming one (script kiddie that is). While there are literally hundreds of thousands of script kiddies and wannabes out there, keep in mind that there are also a good chunk of true hackers as well, who are able to spot and exploit flaws in other people's code, write their own code, etc.. basically anyone who claims to be a hacker, isn't one. Unless of course they are asked by someone for their opinion based on their particular skill-set.
Script kiddies will use and abuse technology to get their name or childish online aliases known. ie. defacing websites through the use of shells, using publicly available exploits to compromise security, download trojans and/or viruses and "pwn" some victims, launch DDoS (distributed denial-of-service) attacks, etc.. script kiddies are generally rejected by society and possess no social skills. There are so many things to be said here, but I think that sums them up for now.
