Our platform is based on “endorsements”, not upvotes or downvotes. Having people pay to downvote invites a whole spell of trouble for people with big pockets who want to censor other creators material. For now, you can only move a post up in ranks by endorsing it. Maybe it could make sense in the future in a different area of the site, but for now — no downvotes or anything similar.
The model is not as simple as you understand it. You are incentivized to endorse a post with a larger tip, sooner, as it increases likelihood of more tippers. And, you can tip any amount- the avg tip amount will vary based on content type and globally what people are comfortable shelling out. It’s a model that’ll adapt overtime, as stated in the text. This is a preview launch. More details will come later.
