Anybody with Admin below their name is definitely me or a trusted person. I myself will always sign as Butterfree. If somebody signs under that name but does not have the Admin label, it is most likely an impostor.
I am actually pretty grateful for the reordering mechanic you are implementing. New pokemon are never going to stop coming out, and it is good to have a means to bump up new favorites to old lists without having to redo the entire list all the way over again. Additionally, I've been using the lists of friends to catch pokemon in their favorites for them, but because I organize priority in my list a different way than they do, being able to shuffle around a personal instance of their list such that I can avoid getting lost in the clutter is very useful. In addition to that point, if you could make a "remove from my list" option, like a little trash bin at the very bottom of the list that picks could be dragged to, that'd be cool. Opinions and emotions change, and sometimes it's just time to let go of old friends, you know?
The code is already all client-side - you can see it just by using the view source feature in your browser. I don't mind if you make derivatives, so long as you credit it appropriately and link back.
Is there anyway you could open source the Favorite Picker code? I saw a Digimon one which said you gave them the code and I would love to do this with my friends for various stuff.
