Can not register, username problem

[Ronaldo Batista]

Hi,

I'm having trouble with registration. Although I have tried to register with several usernames, I always get the error message "The username you entered has been disallowed or contains a disallowed word. Please choose a different name."

I'm using an email address associated with my university and also tried another one from protonmail.

Any hints for solving this?

Cheers,

Ronaldo.

Are you using "Ronaldo Batista" as the username?
