Im my recent scamming attempts i had gotten many frozen accounts. This annoyed me that i could not even tell what characters the account might have. So, i was playing around in the Account Management and an Idea hit me...Character Copy onto PTR.
After seeing this all it took was to go through the realms( I know, this step takes a while ) and check which realms have characters. Now that you have found out what different characters are on the account, you can trade for legitimate accounts easier or decide whether you want to just keep it for yourself in the shape it is.
I found this helpful, so I decided to share it will everyone as a little tip
Anyways, good luck scamming all!
