A bot automatically spamming a message on 1000 posts a day is not the free and open sharing of information. It clutters the platform and makes the actual content less visible and accessible.
Stealing someone else's work, or impersonating them is illegal, and could lead to problems for SteemIt down the road for allowing content infringement without attempting to police it. Citing someone else's work and creating your own content/commentary on their work is perfectly ok, it's theft of someone else's work that is prohibited.
