I frequently see users across all communities with a display name of "user" followed by a bunch of numbers, or in terms of a regex, user\d+. This doesn't seem like an elaborate username choice, so what's going on?

It's been more than a month since I have started using . It has these users with user names in the format of "user-random number". I have observed them in some of the stack activities, most of the time asking questions.   Does the moderators create them for their own purpose. If yes what purpose do they serve?   I mean a user is free to have any user name. But it's just a hunch that such users are actually moderators. I may be wrong; just need some clarification.

What is the format of  account names?  The information I have a use for is:   what characters are permitted or prohibited? what is the maximum length? are they always treated as case-insensitive?   However, a complete, exact definition of the allowed format would be appreciated.

There are users listed under the "Users" tab. How do I know who the moderators are? Is there any specific thing to look for on a user, I mean a icon or some other sign? How do I contact a moderator? Is the a way other than using "flag" link?

E.g.: If your Gmail ID is abc.xyz@gmail.com, it considers this the same as abcxyz@gmail.com.  Why is this so?

While browsing the  I came across the synonym [vote-to-close] -&gt; [closing] in which the creator is listed as &quot;anon&quot; — the username is not hyperlinked, just like how the user IDs of deleted users are listed in other places like in the list of close voters of a question, etc.  If this really were a deleted user, then I would have expected their user ID to be shown, and not &quot;anon&quot;. So, I checked using  for data on the tag synonym. And sure enough, it shows that the deleted user with the ID 147263 created the synonym. To double-check, I looked up the  and came across a bunch of synonyms created by &quot;anon&quot;. Checking with , these were all created by the now deleted user with the ID 80. Similarly, in the  there are several created by &quot;anon&quot;, but  says that these were created by the now deleted user with the ID 54262.  Feature request: Show the user ID of the tag creator under the &quot;Creator&quot; column in the list of tag synonyms if the user is deleted, to be consistent with how posts and actions by deleted users are attributed everywhere else.

I was surprised that I didn't find this question already on the site. So, today $ came up after I logged in as a new user. This was unexpected because my main user's prompt starts with username@computername:~$.  So, how do I switch from this other shell to bash?

In the /etc/passwd file on my system, the "comment" field, field 5, is inconsistent in its contents.  I thought that I could extract it to get the full name of the user.  fullname=`awk -F: '$1 == name {print $5}' name=$LOGNAME /etc/passwd`   However this returns with $fullname containing a name with 0, 3, or 4 commas following.  Exploring the man page (man 5 passwd) provides no details of this field other than describing it as "user name or comment field."  Perhaps there is additional information that is stored along with the user name?

After finding , I thought about inspecting Community's ♦ profiles. What did I notice? Community ♦ have more than 1 rep on some meta sites.    - 5 rep  - 3 rep  - 3 rep  - 3 rep   Why is it?

The long name pushes the stats to a weird place. And what's with the "Stack Exchange" at the end anyway?

I just noticed . Hey! I'm there! But that's beside the point.  The point is that Nick Craver is there too. Nick seems to like really long tag names, so his profile shows up like this:    Akk! Diamonds everywhere!  It seems that the page is optimized for only two lines of tags per user. One tag per line means three lines. Three lines means that Nick's reputation (tag) is cut in half.  Let's not cut Nick's rep (tag) in half on the Users page, no?

How I would go about getting the current users username or first and last name?  I have been looking at this for the last couple of hours - I was just wondering how I would go about getting their name and then displaying it on the page.  For example the current user is 'John Smith' and in the lightning component I want to output John Smith's name like:     Welcome to our community John Smith!

I just saw a user named: .yahoo.co.jpaqwsykcj3aulh3h1k0cy6nzs3isj  Could new users be named according to their user-number, or something other than "Unknown"? Perhaps User1234567 instead? It would be less awkward to address them in answers and comments.   Additionally, I often times have to check profiles to make sure users aren't abusing the system, since I find many of the same questions from "unknown (google)" from time to time. That, or I'll mistakenly think I've helped the user on a similar issue in the past, and assume the user has knowledge that he or she does not have.

Many websites when ask you to create a new "username", will limit you in some way, most often like "username should only contain letters and underscores" or something alike.  This results in inability to use my email as username and forces me to come up with new unique string all the time.  What is the rationale behind this?  Why not just let users use their emails, as a simple to remember and always unique?   What is generally wrong with having symbols like *&amp;%$#@ as a part of username?

When clicking between "Week", "Month", "Quarter", "Year" and "All" on the users page, the name I have typed in to filter on disappears. I feel like it should stay there, so that I can type in my name, and see how I've done in a week/month/etc.

I was changing file permissions and I noticed that some of the permissions modes ended in @ as in -rw-r--r--@, or a + as in drwxr-x---+. I've looked at the man pages for chmod and chown, and searched around different help forums, but I can't find anything about what these symbols mean.

I just took a look at the Recent Badges column and the high frequency of occurrence of a username caught my attention:    I then visit the links of these badges to see how this user (jrharshath) earn all these badges at once. It turns out that these questions are quite old and he should have earned them a long time ago.  Famous Question:     Notable Question:     Good Question:     Why did he earn all these badges at the same time?
