Quick question about JAG.

Hey Sythe, I just started playing the 2007 version of Runescape and have a question about JAG. I just bought an account from someone, and I got all information regarding its info, (First password, second password, ip, even cc last four digits) but I'm almost positive this seller won't take it back. I don't want to resell it for several more months. If I were to set JAG on this account, would I be able to disable when I wan't to resell it?
Thanks.

 

Once JAG is enabled - selling it becomes difficult.

You can have it disabled, but the questions will need answers when sold and it seems sketchy as you can always get it back by answering those questions.

Selling accounts when you're not the first owner is also very sketchy.
