I was simply thinking the original blog post provides the same copyright proof, regardless of what is posted on FR afterwards.
But I am ready to learn more.
FR is honest, I don’t worry so much here.
Anyone can read it. No membership required to get access to cut and paste. I have no illusions about material being "safe" here. But I just don't see that any different than a public accessible blog.
Most people here won’t do that.
It seems to be a VERY conservative thing - respecting the person who creates what you are reading.
