Welcome to the big bad world of ebay selling.
You do not need to provide any documents when you register to sell on ebay.
But as soon as you do a reasonable amount of sales or listing product crossing a certain value, you are asked these documents.
Fulfill all these and you will be allowed to sell on ebay.
At one end ebay wants to make entry (as seller) in ebay very easy and thus there are no entry barriers.
At other end the T&S is scarred that all sellers will defraud all the buyers and ebay will be held holding the bad. Hence this ridiculous suspensions.
There is nothing anyone can do about this.
This has always been the way of ebay and this is how it will be.
Keep smiling ......
