Hmm.
Well, if most of the social platform users tag out from Steemit, due to these (hypothetical) malicious flaggings, then there's nothing to invest in other than what essentially amounts to "vaporware" (no real value).
I think it's clearly a key to keep the majority of the social user-base happy, no?
EDIT addition:
Also, I'm not convinced that what works in MMOGs will correspond one to one with what people will support when they have thousands of dollars at stake and real flesh to protect.
I'm not even claiming that it works in MMOGs (consistently at least). It was pointed out to me that it does happen in some cases, so I commented that if it did happen here it would be good for investors.
I'd also note that it is very speculative at this point what will build a user base that is significantly above zero (on the scale of successful online social platforms) as well as what would keep such a user base happy. This has not been demonstrated at all.
Competing with established platforms that are more specialized to the task of focusing strictly on user experience is not an easy task. Steem/it needs to focus on and somehow exploit its unique advantages. In a big way.
