Does your sister know that you are are powering down her account and sending the funds to your two accounts? I think she wouldn't be very happy about that. She seems to know her way around Hive very well, I can't imagine she wouldn't know how to power down her account by herself.
The whole things seem shady, and neither of the three profiles have ever made an #introduceyourself post. For me, I would like to see an #introduceyourself post from both you and your sister, something you both have never taken the time to do in all the years on Hive/Steemit.
For proof of brain, I'd want to see you holding a piece of paper with your Hiver username on it, along with the date, and the same for your sister too. I honestly don't feel comfortable curating anyone that's never done an intro post, that is one of the biggest signs of farming accounts.
Take a look at my intro post for reference.
