If Zeref were so easy to track CS won't have to travel for 7 years trying to search for him. It's the same for Crime Sorciere, if it was to easy to gather info on them, they would be captured long ago. Acnologia despite his size can't be traced easily, why would Zeref be easily traced. Plus CS used 7 years yet they have little info on Zeref, if Lucy accomplishes it in a year, i'll definitely consider it a BS.
