If a person elects to download something, they should pay for it.
If it is wrong to do it a lot, then it is also wrong if they only do it a little, even as little as one time.
If someone came to my place and took something that did not belong to them it would be stealing. It is no different here. So why is it not a big deal if one person steals from another one here?
At the very least the payment for the item/s could be deducted from their account.
Besides, if someone from the outside did this, would this be "no big deal?"
This is no different then if someone logged into Tradebit's Paypal account and helped themselves to some free money or to a fellow merchants' money! If the took a file worth, let's say $50.00, they in fact have stolen $50.00 from that person with the aid of a known, long term security problem within Tradebit.
This is a great site, I have not found anything like this place anywhere else.
