I have a friend who wants to sign up with the alias he uses all the time, but the sign in says it's taken. Also weird variations are also taken (eg. SS_nickname, XR_nickname, etc.) if I search for his desired nick I'm the search box, (like u/nickname) it says there are 24 results, but only shows one and it's similar but not the same.
Should I assume searching for user names is broken or am I missing something?
Thanks and sorry if I should know this.
