Steemit gives us information that we aren't always used to seeing expressed directly in a numerical fashion - namely, that some percentage of people will likely hate us, no matter what we do. Sure, rewards are totaled, but downvotes are treated in a special fashion with their own icons and functions such as hiding posts, comments, and images.
Steemit is a social network that take almost 95% of someone's time. It can't be compare to other social network in all aspect.
I think is okay and proper to down-vote, hide image,comment and post. Before an account is down-vote on steemit, there will be a numerous warning before action.
Unfortunately, this does not appear to be the case except sometimes:
"Before an account is down-vote on steemit, there will be a numerous warning before action."
Although:
"Steemit is a social network that take almost 95% of someone's time."
You got that part right.
