That's not true in every case. Sometimes people do it just to be jerks or to de-rail a thread. Here is an example:

Haha, you actually made a thread because I 'de-railed your thread just to be a jerk'? Dude, calm down. You get annoyed when people tell you to buy games? Think your the only one who ever gets annoyed? Its annoying when people make dumbassed threads about easily researchable topics. I also find it annoying when people can't wait for a "solution" (solution is in quotes because there is already a solution out there) so they can play their downloaded games. If you're not paying for games, or contributing to the scene, you have no right to complain. If you can't wait until 2009 for a "solution", then do it yourself.
I have a Supercard, and I download games for it. I help people when they're having problems getting their pirated games to work and I know the answer. Find a healthy medium, you don't always have to be to one extreme.
And sorry if I hurt your feelings by de-railing your thread and being a jerk.
