Some quick tips about buying and selling Origin/EA/Swtor accounts:
-There is no way to separate ToR from Origin
You are able to change the email and pass on Origin (either through the program itself or profile.ea.com) and have it be different from ToR, but this is only temporary. There is a lag time, but eventually TOR syncs with Origin (took about 12 hours for me).
Please be aware of that if you are buying, and be sure to also log in through Origin.
-If you bought the digital download version of ToR, your credit card and billing information has been saved on Origin regardless of what options you chose (remember when they had you nickname the CC?) and the only way to remove it is through EA's customer service.
You can view your information when you try go through the checkout process with another game
CS will try to tell you that the information not in their database
Eventually they logged in to my Origin account for about 2 hours and deleted the information
-If you bound a TOR Authenticator to your account, there is no way to remove it except through customer service
Once removed from whatever device, you won't be able to bind another Authenticator on it or it will lock you from the account (they'll warn you of this)
Enjoy the cluster**** and good riddance to EA
