If someone owns material and can share it in full on FR, but chooses instead to “tease” it with one-liners, that isn’t “sharing,” it’s spamming.
Nuff said.
Excerpting a blog may be wrong and not cool, and even against the rules here at FR, but that is entirely different than theft.
If posting a link to a blog is theft, then so is posting a link to a commercial site. Simple as that. Without links and content from other sites (commercial, blogs, et. al), FR does not exist as we rely very heavily on content from others.
I don't have a blog. If I did, and I wanted to share something with Freepers, I myself would post the article in it's entirety. I don't have an issue if others only post excerpts and I'm not nanny enough to police the internet. If an article intrigues me I read it. If it's an excerpt I make a decision as to whether I want to click the link to read the rest. I'm an adult and that's what adults do. If the poster is breaking the rules, the moderators can go ahead and remove the post and even ban the poster if they are habitual rule breakers. Calling them a thief is uncalled for in a civilized society.
