How do I know if something is plagiarism or acceptable under fair use? I mostly post in photography, and I have noticed many high earning posts that simply cut and paste, then give credit at the end of the post. One user who does this is also listed as a witness and has been profiting handsomely. Honestly, during a bout of frustration, I tried the same tactic (didn't work for me). Should I flag this or upvote to get some curation rewards?
