Is there anyway to find the IGN for an account from the forum name?

I'm trying to locate my old crossfire account that I gave away a while back. I want to see its final resting place because I forgot what was entirely on it and want to see where it got overall. I am not trying to sign back into the account I just need to find the IGN as it was changed to some CTM_####### name. I have the forum name and it hasn't been active since 2016. Other than that I have tried to use the wayback machine to find the link to it, and signing into old accounts to find it as it would have been listed as a friend.

Does anyone know a way I can find the IGN of this account in general or based off of the forum name?
