Yes, and for the reason that prices of accounts have dropped significantly in the past couple of months. I am sure you could get a lot more for it if you sold to one of those other websites where you have to provide personal details (For example, ID or Passport).
Furthermore, your bank is not $500. GP is around .4 and less for you selling it to someone.
Take what I said with a grain of salt if you choose. I would be happy if you proved me wrong and sold the account for $3k+
