I've noticed that trolling seems to be a bigger issue post-HF19. I think that once they discover it's not a profitable endeavor, it will subside, but in the meantime, it's definitely made me grouchier and less likely to interact with other users.

Perhaps these other community members are feeling the pressure of having to deal with newer minnows who are clogging up their communication channels with spam in pursuit of a valuable upvote? (I'm not implying that's what you're doing, just that they may have banned indiscriminately because of other people doing it.) The HF makes the platform attractive to a broader audience, but they don't understand Steemit etiquette when they get here. Once they get the hang of it or get downvoted into oblivion, I think things will get better.
