@heimendanger, not exactly like d.tube, but absolutely we are running a business on the blockchain. I have written well read posts about that in the past.
We are incorporated in Seychelles and our offices are in Dubai and our Banks are in USA, UK and Norway. If you need to speak with me or any of my team, the best way to reach us is through http://STEEMspeak.com 24/7 on the voice-chat, but if you want to send anything written you can fill out the contact form on http://fyrstikken.com.
Our TOS are explained in the steem blogs of booster and speedvoter and we continuously develop on it to make it better and better along with 20+ other apps/smart scripts we finance through partnerships with @inertia and his company so he has enough funds to keep them up to date as we move forward.
If you are looking for sponsorship for something great, we set aside power for that and is something we can talk about later when you have calmed down some more.
Fyrst.
