the same username

Yes. It was a very exciting experience ever.

Its really surprising to know how can it allow same id , i think id will be unique thorught the website , it will not be repeated. its really surprising to know the username are repeating may be with the use of mixed language , but that website should not allow similar username, you better write a mail to that contact of the website developers

i experience this one time but a long time ago. i thought i really have a very unique username. but in most sites that i have joined so far, mine is almost available.

Actually I have a friend whose first name is your user name minus the numbers. It is very rare to get a 100% unique user name, I worked hard on trying for a unique one with mine and I have seen it elsewhere on occasions. The best you can ever do is just hope for only a rare few people to use the same user name.

I experienced very little. Only once I register a novel reading site, I found my ID usually used was registed. I've never seen there is anything on the internet has used Id i'm using. My ID is really unique, haha.

this can easily happen if you have a common name and just add numbers before or after it and then use it as your username
