How to check in blog use copyrighted material ?

 Big Solution about copyright explained

If it doesn't have a copyright notice, it's not copyrighted.

If I don't charge for it, it's not a violation.

If it's posted to Usenet it's in the public domain.

My posting was just fair use!

If you don't defend your copyright you lose it. Somebody has that name copyrighted!

They can't get me, defendants in court have powerful rights! 

Oh, so copyright violation isn't a crime or anything?

It doesn't hurt anybody -- in fact it's free advertising.

They e-mailed me a copy, so I can post it.
