I totally agree people shouldn't just blatantly copy someone's work and post it with the original link. Steem should promote creative and original work more. Steem is a great way to post your content, post your progress and make a little money off it, it shouldn't be used to post other news articles!
Edit: What is the reason for people to upvote their own work?
Greed and/or stupidity imho.
Thanks for commeting. @firefoxit is not just about copying original content, its also autovoting comments and rings of voting collusions among others.
