Hello. I hope you have a good Christmas and winter. Since it's Christmas and old things have to be replaced by new things, I decided to change my handle. My name is Ehsan and I wanted to change my handle to my name, but unfortunately, someone owned this handle 14 years ago, but when I changed my handle, to my surprise, his handle was taken and given to me! I wanted to say that if you want the old handles, this is possible! And my question is, how did this happen?
You're able to take the handles of inactive accounts, but they can take it back if they want to. More info: https://codeforces.net/blog/entry/123590
Oh.this is so strange. Thank you.
