I got banned

Hello dear admins, year ago I got banned of suspicious activity cuz I wanted to exchange my account online to some guy and now I got back to clash royale when I find out about this site, one of the questions that support asked me is what is your old nickname, I answered all of others questions but this one won’t let me pass the test, can you tell me my old nickname pls this is my id #PY0UVPUYG I remember that I got banned before legend troops like skeleton king have came out and my nick was kakasi sen( don’t mind it, I was stupid)

This is just a link to my account?
