Sure, but under what license is it made available. If I find some source code floating around on the internet while looking for the solution to some problem I'm having, knowing what license it's under is kind of important.

How often does that happen really? I can't recall the last time I saw source code where you couldn't tell:

1. What license it's released under. 2. Who you can contact to get permission to use it.

If there's really no way to tell who the author is or what license it's under, then I'd say not to use it. It's probably better in the long run that way anyhow.
