Let me correct the "unwarranted" statement. The feedback itself is appropriate. It just isn't necessary. That's what I should have written. I am in no way criticizing you for negging this guy, because I wouldn't trust him either.
Yes please. It's quite a nuisance to be attacked for something that isn't necessary but is appropriate masked under the reasoning that it isn't appropriate. This is a general statement based off of sentiment over the last couple of months, not particularly saying that you've been attacking people! Content theft is by every definition stealing, therefore a trust-related action. How do we handle plagiarism? Forum staff bans the users. Should we vilify people who leave negative ratings for plagiarism, i.e. scamming? No.
Fork your own words if want fork. Stealing is a no go.
