As the Creator told me, there will be a changelog in the profile, so it won't be possible to "hide" it. If abuse starts, we'll shut it down.
Although, I was thinking that changing the nickname 3 times a month might be too much. I think once every 3 months would be reasonable.
It would be even better to do it no more than 1-2 times a year! And when viewing the profile, the changelog with all previous nicknames should be visible to everyone.
