Co-incidentally, I came across this post this morning by @thedarkhorse.
"Just because you can doesn't mean you should."

Basically, it is saying to exercise restraint. Newbies might make mistakes but after a while one should get an idea of what he or she can do and what he or she can't do. Just because there are no rules saying you can't do something doesn't mean you should do it. Some things are frown upon, and it is basic human decency and human courtesy not to do them.
Unfortunately, there will always be people who try to exploit the system. So, it is great that people in the know on here can step in and caution the culprits.
Hopefully, all can play fair, play their part so that everyone can have an enjoyable experience here on Steemit.
