In my other article, I have written about how to unlock Locked ID. What is the difference between Locked ID and Banned ID? It seem a same thing because Locked ID and Banned ID also can not be used to login in yahoo messenger. An easy way to understand the difference between Locked ID and Banned ID is, Banned ID is Locked up ID COMPLETELY. Usually an ID who got banned because of again the rule or Term of Service of Yahoo Messenger.
How to unban your banned ID? If you want to unlock your Banned ID, I will give you a tips to handle this problem, but, you should know that I am not guarantee this tips will work properly. I found this tips from my friend, I you want to try, just read this note properly
First, go to your language setting. Note: Even though your ID got Banned, you can be login to your account setting via browser, but your ID never be joined via Yahoo Messenger. After you have login to your language setting in your account, change the language to Chinese-China (Yahoo Mainland). Save it all then exit out of it.
DO NOT try to get back on your name for anything for about 2-4 weeks or until your ID unlocked. Thus, you can change your language setting back into English. After your ID unlocked you can login and have fun with it. How is it work? Yahoo server will detect your ID (your banned ID) as a new member ID but, actually, you are not.
If this tips doesn’t work. Try to stay in Yahoo Mainland much longer. You can put your ID in Chinese language about 2-3 month before you got it back.
