ebay and Amazon both have a business practice of closing peoples accounts and holding onto their money between 90 and 180 days. They also make money on this money in the form of interest while they are holding onto it. This practice of making money off of sellers by closing their accounts and holding onto their money needs to stop.
I'd also like to point out that it's ebay's financial processing arm, PayPal that actually holds onto the money of ebay sellers.
