What do you mean by an antilicense? If you don't want to impose any restrictions on people, just put your code in the public domain. Here's some boilerplate for that: http://unlicense.org/
But you can't expect everyone to do that. Considering people who exercise their rights under copyright a "problem that needs to be solved" is generally regarded as a... radical stance.
If I use things off SO I link back to them, out of courtesy to future developers.
This is a problem that needs to be solved though, too many tutorials have code under restrictive licenses, and it doesn't make sense to me.
