You can say what is suggested is similar to tripcodes used in some imageboards. If you put `User##password` (where `User` is optional) in the name field when you post something your name will be displayed (differs in each site) like `User!!rEkSWzi2+mz`. So your "account" is the password, no username is needed, and you can have a nickname if you want.
