Good point about flaggers. I will say that I know a fair number of people who use multiple identities to make Steemit posts (either to try and attain some anonymity, or to cheat the up-voting system). On the mobile apps it is relatively trivial to flip between them.
At the moment Steemit has a relatively small user community in the few hundred thousand range. Although I think proportionately we might have a few more "fringe" users than elsewhere we don't seem to be anywhere near the absolute huge numbers of "dicks" that tens of millions if not hundreds of millions of users would bring.
Too many dicks - that pretty much sums up many problems in life :-(
