I do manual curation, auto curation and a little vote selling assuming there is anything else left (there often isnt). I know it's not an excuse but I'm only a small account.
I have been insulted on steemit, in fact very vigorously by a group, because I dared to point out that they were pedalling opinions as facts; that made them really angry. It wasnt nice but it was a while ago and I can laugh about it now ha ha, though I don't think any flagging occurred.
I definately see much more abuse on other platforms (not aimed at me but as a spectator), Reddit is pretty bad a lot of the time. Overall steemit is a much nicer place to be.
