Hey, @fernandosoder.
I agree completely with your choices 4-11. The first three, I'd need more convincing, I guess, since I see the typical big investor as someone who doesn't really have time or desire to get on the social side of things and see what people are saying or doing.
That's not to say they shouldn't, or that your 1-3 aren't something to be concerned about—I just know that people have their own definitions about what constitutes those things, and to what degree, and none of it is really prohibited or policed, other than what some users might attempt to impose on others.
I also wonder to what degree any of that truly affects STEEM. Especially now, with the EIP in place.
