sgr-wholesale. you can get back on, but you have to do a few things first.
open a new bank account, or get a prepaid visa card wit at least 50.00 on it.
then get yourself a new pc. if you cant afford to purchase one you can always lease on from one of those rental places like arrons. blue hippo is also a good source you can find them online.
once you do those things, you can then create new accounts with both ebay and paypal.
let me also say, ive known people who used the same pc, but a new bank account. and it worked. so im not sure about the pc part.
