In short answer: No.
Selling and/or purchasing an account from another user is a serious violation of the terms of service. MocoSpace does not provide a safe, secure means to trade or sell accounts among our users. Your information could be compromised either way and personal information may become available to either party in such a transaction.
We ask that you NEVER be involved in either end of such a transaction. The risks are far too great for any user to take. Advertising any where on site, or if sufficient evidence is provided, that you've purchased or sold an account, the accounts involved will be terminated for safety precautions.
