I legitimately have a younger sister to plays Neopets and has invested quite a lot into her account. I'd feel pretty guilty about her getting chain frozen with me.
If you two don't share the same computer/IP then you shouldn't have anything to worry about. If you plan on cheating and someone close to you, such as your sister, has legitimately put much into her account, BE SURE that you're not 1.) using the same computer and 2.) share the same IP address and you should very well be safe in the off chance you got frozen.
As always, be careful
