For people on the tribe sites new to ViT if i may, quote https://vit.global/@viceindustry
"This tribe is basically about Vision Industry Token (VIT). We have our own blockchain with a couple of front ends powered by VIT. VIT's primary (but not sole) focus is on the adult industry. It is a place for adult content creators to share their work and be rewarded by the curation of the VIT community. This tribe is essentially an extension of our existing community on the VIT blockchain. It's a new meeting place for the VIT and Steem communities to comingle."

Accounts on ViT are free.
The two front ends mentioned are
https://touch.tube/
https://touchit.social/

One for video uploads, the other for social nsfw posts/blogs including nsfw pictures and other Adult content.
Its attention economy model can be incorporated into pretty much any website, not just the ones Vit operate.

It's payment gateway which enables website owners to accept vit as a payment for goods, is operational within wordpress sites via the ViT woocommerce plugin,

The tribe site is just a small segment of what ViT is and ViT is not bound by the steem blockchain and is amongst other places being used to pay for VIP memberships on 'red light centre' and soon to be hologirlsvr.
