Sorry for the wonk title but I'm a small fish in a world full of bang and flash.

Question: can Neo staff go through your item transfers after you've frozen an account. Not talking about if someone is trying to scam someone else and then freezes after ripping someone off. 

Hypothetical:  I bought an item, it was transferred to a shell. I leave item on shell for a little while then transfer to main account and freeze shell. (two different IP addresses for main and shell).

Are they likely to ever go back and figure out what's going on? Is this relatively safe?
