I have been reading the faq lately in planning my purchase. There are a couple of things I think could be done better. Notification of the 3% sharing fee of post rewards and more information about what this tribe sees as a quality post.
The 3% is actually already a decreased amount. It was 10% in the past, so they took more beneficiaries in the past. The beneficiary decrease from 10% to 3% was 7 months ago (on 2019.09.24).
