United Bitcoin also seemed like an overly-elaborate attempt to encourage people to spam the Bitcoin chain (which has been running close to capacity) with junk transactions by promising them tokens if they did.

Wow, quite an elaborate scam to buy such a domain. Just curious, can anyone give a price estimation for ub.com?

Also the method to "claim" it requires you to make pointless transactions to your own address in the BTC blockchain, just adding to the congestion.
