However, one should think why would someone go with all the hassle creating so many Rainbow related accounts.
User kxwhalexk was a fan of user RainbowKun, and created several accounts on his behalf. RainbowKun created one alt account to use later. A day before he created RainbowDAO, he posted this:
In the next two to three months, I will officially launch a blockchain DAO project, which I call Rainbow City.
The other usernames were taken, so it makes sense he for RainbowDAO.
