There's a fair few I 'd like to see leave or at the very least change their behaviour. :-)
I'm not going to get upset about someone who goes on funded holidays by the places they visit to write reviews about their hosted location. And then re-posts that stuff on steemit but sticks the steemit logo on the pictures to give the pretence of exclusivity. I have no issue with sweetsssj personally what I disliked was the fact she brought over a lot of followers from her other sites and then started hoovering up votes that could have gone to less fortunate hard working minnows and from what little I saw rarely if ever rewarded comments thus spreading some of that good fortune around.
Again, that's just how I feel about the subject. Your view may well be different to mine. :-)
