Their news announcement says that they want to ensure that a nickname and a channel should always be able to be registered first by a human and not a bot.
They do that in response to a trend they noticed where they reportedly have “seen increases in bots getting nicks and channels, holding them, and never releasing them” and continue to say that it’s “not fair to the average person that a botnet gets a nickname before a human does”.
