Last time I checked you're not one of the judges. If we begin to walk through the path you're following then we would nominate everyone not minding how active they are. These ones you mentioned, how active are they? The person I nominated has been adding so much value to the blockchain. Go through the blog and check.
I could give reasons why your nominations are wrong but I wouldn't want to drag issues or spoil someone's favor. I repeat. Allow the judges to decide, they are not daft, neither are they blind to see.
If they told you to help them check, then I'd not bother. The ones you mentioned could be fake accounts anyways.
Just nominate whoever you want and allow judges to decide. I won't give you another reply but I do hope you'll learn to mind your business.
You are correct, I am not one of the judges, but everyone is free to express their opinion.
He has been actively upvoted/upvoting posts on a daily basis since many months, but he started to be active with resteeming 4 days ago (2018.10.18), and he wrote his introduction post 14 hours ago (2018.10.22, 03:46 CEST).
Their accounts are just two examples, and they could be fake. There are a lot of people with small amount of Steem Power on Steemit. @jhayehidio is registered on Steemit on 2018.03.06. @darknyx is a new user, so we currently can't talk about how active she is. She is registered on Steemit on 2018.10.13.
