Strange username suggestion on the forum sign up for usernames starting with 'brave...'

Hey backend developers,

I just signed up for community.brave.com and wanted to pick a username starting with ‘brave’. No matter how you continue the username after the initial letters ‘brave’, the usernames are always shown as taken and a cryptic alternative is suggested instead.

E.g. ‘Not available. Try 40d330c74ad01d3afcf3?’

A straight forward hint would be less surprising if this is intentional.

Kind regards.

Hm, I wonder if it’s so people don’t sign up and give a false impression that they work for Brave Software.

Yeah I guess that, too. Only the nonsensical alternative suggestion made me think it may be by accident. Because when you enter other usernames already taken, you get ‘sensible’ usernames suggested instead.
