I think the only issue you had is upvoting the same people. If you will upvote more people from pob everyone will be happy. I also had such an issue. I wrote about that a big post, it's hard to support everyone of course, especially being a leader of a community and as I see, you are kind of a leader for Brazilians.
I also was lost as a leader of @dcooperation especially when moving from PoS to PoB. So, I decided to distribute my curation among the members of the community, all the tribe here and newcomers. That I think will be a fair thing to do. That's the only way to avoid any conflict of interests !
