There's downvoting because someone doesn't like your content or it's in the wrong category, but I think the OP is talking about systematic retaliation where you make some comment supporting a user who is getting bullied and then have every single post you make downvoted by a bot farm for an indefinite period of time. Fear of retaliation along these lines has been keeping me out of these discussions. I don't know if there's a way to be involved in anti-bullying/anti-abuse on steemit if you're a minnow. It seems like you need a whale on your side.
