Currently I am creating a website which communicates with WHM via the WHM API 1. At this moment I am creating a username verifier (to check whether it is valid and available) since there is no API function for it (right?). At the API documentation page of creating an account it says the following: Just now I created a new user via the WHM interface with username 'fakeaccount' - 11 characters, I am running WHM 11.50.1 and have database prefixes enabled. Is this restriction recently removed? Besides that; is there a place where I can find a list of reserved usernames? Currently the most recent list I found is from this topic (started in 2011).
