errr, so how are we supposed to share information? I'm not submitting a journal report to be peer-reviewed mate, and do you propose that everyone reword everything they wish to share?
You might want to flag everything I post then, because I use this service as a middleman of information networks.
Copy pasting is stealing. Period. If you want to share something, you can always share the link, quote a few sentences and comment them. That is what is called an original content.
Also, what do you think the initial author of the post will think about someone copying his/her work without permission and getting money out of it?
