Adding 'anonymous*' to reserved_usernames blocks creation of 'AnonymousXX' name structure in Anonymous mode

[JammyDodger]

Do you have a lot of anonymous users?

Anonymous Username - over 100 users

We have really weird issue, up until user 100 the username was in this format anonymousxxx e.g. anonymous10, anonymous55, anonymous100 However as soon as we reached over number 100 anonymous user accounts, they are now in this format: 9ab9441ad3316f5d2d35cd4807317cc 01c3b651778b7871a7640511daa8eb8

I think this was fixed at the time, but there may have been a regression?
