AFAIK anybody can use stackexchange sites, as long as they follow and/or accept site rules and policies.
As far as AU is concerned, anyone with a Ubuntu question can ask a question, it may be a person, a group of friends, It can be a company or even a government. For the same reason, a user may be a company and therefore they can promote(in their profile) ...
User ID in the sharing link is useful in at least one situation.
There are some badges:
Share a link to a question later visited by 25 unique IP addresses. This badge can be awarded multiple times.
Share a link to a question later visited by 300 unique IP addresses. This badge can be awarded multiple times.
Share a ...
Logical simple way of viewing it lets us divide this in 2 types of spam:
The post related to the question in case (as in: it could be an answer) but connected to a commercial product/information or owned/developed by the user;
The post is pure spam and has nothing to do with the site or the information we normally deal with;
First case should make us ...
I approve if they aren't obviously a vandal. We can't do a IP check, or anything like that so its a little difficult, but again, if it isn't vandalizing (and adds value to the question) then by all means, approve it.
Using a domain name as your nick won't actually link anybody anywhere other than your profile. It won't attract Google rank or any other benefit.
And in this case it looks like they've already change it by their own volition.
There's a difference between imitation and just having the same name.
Example: 2 people named John who create an account with the same display name. The profile picture will most likely be different.
This is the case when two users just happen to use the same name, and is completely OK.
Example: 10 ...
If you have never voted and have only 1 post you can delete your account yourself from your profile. Under "Edit Profile & Settings" click "Delete Profile".
You can't delete your account yourself if you have more than one post and / or you have voted on the site. If you want to delete your account after making a post or voting on other posts, you ...
Usernames are not unique. Anyone can name themselves anything they want, as well as rename themselves whenever they want. As a demonstration, go to Users and search for John. You'll have hundreds of hits.
The system instead uses user IDs as the authoritative reference. For example, you are user 772394, and I am user 208574. Thomas Ward (the mod) has the ...
The transactional database doesn't care about some arbitrary nickname but id's. As you have (I presume) noticed, everything has an ID in Stack Exchange, posts, tags, revisions, and users. So, your nickname is linked to a specific ID in the database and that's shared in all the network. So, to answer your question, yes, there can be two users with the same ...
To delete your account just follow How do I delete my account?, essentially:
While it's strange nobody answered in fact it's not at all necessary to contact the probably busy mods for an account deletion.
Spammers are attacking every website. That's what spammers do; they spam.
Just flag the posts you find. If enough people flag the system will take care of things automagically. Otherwise a moderator will nuke the post when we see your flag.
We don't need a Meta post about every instance :p
Add a new login before you nuke your Facebook account.
If skipped that and now you're stuck without a login, I'm sure the nice people at Stack Exchange might be able to help you provided the other account information (email, etc) is valid and really is you. Use the contact us link at the bottom of the page.
You've contacted us 4 times over the past 13 months. Each time, we've responded with instructions on how to delete your account. Each time, we've gotten no response until the next time you contacted us.
My guess is that you spam-blocked all of our responses. Makes it kinda hard to help you, y'know?
Anyway, I'm glad you finally asked here - as your profile ...
Just to clear things up, this is called "User Flair", and exists on the StackExchange network data for a user under the 'flair' tab, or accessible by specific URLs such as the site-specific one:
... which only shows the reputation on that specific site, or the StackExchange-wide one:
unregistered vs registered
Your original account was unregistered - this depends upon your Web-Browser remembering your login credentials via a cookie.
If the cookie is lost, then your login credentials is also lost.
You now have registered your account thus you no longer have to depend upon your browser.
Your old account and new account have been merged....
You've been a member for almost 30 days. Hence, the first time you changed (read as created) your username was about 29 days and 2 hours ago. In 22 hours it'll be 30 days and you can then change your user name.
Obviously, there are only certain things I can help you with directly and Stack Exchange will only help you if you can prove you own the main account. Just saying it's you isn't enough. I can give you some clues though.
The Stack Exchange OpenID this account is associated with is not the same one as that on your other account. That's why you keep ending up ...
As jokerdino♦ says, this is because your browser shows links to pages you've visited (via the exact URL the link uses, that is) in one color, and links to pages you haven't visited (in this way) in another color. (This is not related to cookies though.)
Specifically, the darker-colored usernames are links to profiles you've visited, and the lighter-color ...
Click the Contact Us link at the bottom of this page.
In the link that opens up, click on Merge user profiles under Account Management.
If you have access to both the accounts (ie; you know the Login ID and Password), you can merge the accounts yourself by following the instructions on that page.
Otherwise, you may fill out this form, to request the ...
We, as moderators, can delete your account. However, I'd recommend keeping it around. There's no real harm in it being here and if you ever do switch back to Ubuntu you'll have your previous rep already.
If you do still wish to continue with the deletion, bet aware that this is a permanent deletion and there will be no way to re-associate your account with ...
Users install Ubuntu, have a problem, and are directed to Ask Ubuntu. It is a boon to Ubuntu users that they do not then have to go through a registration process to get help. It's a strong message that the Ubuntu community wants to make getting help and using Ubuntu as easy as possible.
Furthermore, Ubuntu is supposed to be an operating system for everyone....
With the new design of SE, the previous answer isn't valid anymore, though the steps are almost the same.
Click your name at the top
Click on "Edit Profile & Settings"
Change your display name and Save.
Note, that you can only change your display on the main site. The setting isn't available if you edit your profile on a meta site.
I host a customisable flair on my website. I wrote the code myself, and it is under the MIT licence. It's more involved than pasting an image into a webpage, but it is a higher quality end product, which is more customisable. It uses the API v 2.2 to get the data. You can change it however you want - move the parts around, chose your own font, change the ...
Emails are not sent as soon as someone posts an answer or comments.
Emails in Stack Exchange websites are more like digests.
The way they work is, if you don't check your notification messages (The ones in the top left, where it says `StackExchange) for a certain amount of time (depending on your preferences), you get an email saying:
1 new item in your ...
If there is no obvious answer to the post then you can:
Flag or vote for the post to be closed as too localized,
If lacking further information necessary to answer them they can be closed as not really a question.
