Mmm only the holder getting deleted is kinda interesting. Legit players have no need for separate holder accounts so my best guess is that they banned you on grounds of benefiting from botting without any real proof. This might be one of those cases where there's a decent chance of having the character undeleted if you can come up with a good excuse for why you kept all that cash on a separate account. Maybe say something like "I got hacked once and lost it all. Didn't want it to happen again." or something similar.
