I included some sites for monthly rewards to whom I feel grateful for the content they provide for free. That went okay. However, I just happened to be on Facebook for just a few minutes and suddenly it was automatically assigned a reward and strangely more percentage than the ones I had chosen. Facebook is the last site I would want as a user to contribute to. They have made millions on contributions of the users and instead of paying back misused their data.
Please implement an option to exclude sites from Brave rewards.
Allow some manual tweaking in Auto-Contributions or implement a manual option.
I am very optimistic about the way you folks are going.
