Yeah I was pleasantly surprised to hear that they had intervened and actually removed the delegated Steem Power. They do have a couple of accounts on here that they post updates on, someone had already shared them with me and I've only gone and forgotten... when I find them again, I'll share them with you.
Yeah, I've found that there are so many nice, friendly and interesting people on here, it's just trying to find them sometimes! I know what you mean, as nice as a helping upvote is, genuine engagement with your posts is what we're really after.
Yeah they're by @anthonyadavisii who is a great user here, he's also made the @randohealer bot too which assists @neautralizer. Yes, they should automatically come and upvote anything that's been downvoted by these scammy accounts. Luckily, even the brand new accounts can only downvote roughly $0.001 at their peak, usually around $0.000 so they really are harmless really, just mildly irritating.
Even if Steemit drag their heels with this stuff, the community here is like nothing else online and they tend to react really quickly.
Good luck with your future Steem endeavours! If you need any help or anything, don't hesitate to let me know.
