I want real original content.

The only reason it should be ok to re-establish from some other source is if it is your own account, when it comes to porn at least.

If it's news people should be doing some kind of summary or an opinion and post the link.

If there is a way to set up a #origional tag I'm all for it..
I'll upvote all content #origional content, till there is enough to satisfy my personal preferences and just vote on that stuff.

I have flagged reposts and will flag them as I notice them especially if the source isn't sited.
