No. Verifact is an independent organisation.
Yes, you can use the website for free. In the future, if you wish to vote, you will need to stake Ethereum tokens, but for now it's all free and points are free and not worth anything.
Users have to stake points when voting, and the "winning" side will receive the stake of the "losing" side. This means that when someone stakes points, they will want to make sure they are voting for the "winning" side.
There will not be a Verifact token sale. It's not necessary for what we're trying to achieve because our system can work on votes which stake Ethereum or stablecoins directly. Or for now, points on the website.
We'll have multiple levels of classification to deal with this problem. The simplest (and worst) category is making provably false assertions. Another category is assertions without any evidence. Solving these first two categories will be a huge achievement and is a big step towards the goal.
Other categories are more contentious. As the network develops, predictable standards and protocols will be formed to make more granular decisions as desired by the community. Examples of categories could include various fallacies, straw man arguments, unethical use of anonymous sources, hyperbole, and ad-hominem attacks.
