I thought I'd contribute this out of my own experience selling game accounts online. Hope it helps out any new sellers.
- Know the real identity of your buyers. Con artists will always try to stay anonymous.
- Keep conversation logs, take screenshots, record everything during your interaction with the buyer.
- Do not trust web aliases or forum reputation. Believe it or not, online rep can be false.
- Be patient. Do not jump to lower prices too soon or make rash decisions because of impatience.
- Contacting the buyer via phone is also a good way to build some trust. Most scammers will avoid this at all costs.
- When using Paypal, it is a good idea to verify your account with a bank. It may take up to a week but it should give any genuine buyers some confidence.
- Get the buyer's picture ID. You may ask them to upload it with a scanner and e-mail it to you. (driver's license, passport, health card, student card, etc.) Also be prepared to identify yourself.
- When accepting payments through Paypal, make sure the buyer's account is also verified with a bank. Make sure the name and information on the Paypal account matches their picture ID. Also get them to send you a small deposit from their account to prove their ownership of it.
- If the buyer refuses to identify themselves in any way, you must be especially wary of scammers at this point. Many scammers are good liars, and they will insist giving out their identity is an unnecessary hassle.
- Written personal identification over instant messaging is not credible in any way. For example, if they type out the information on their driver's license over instant messaging, they may reason that its too much hassle to use a scanner. Do not trust this.
- Buyers may insist on using a 'Middle man' service. Be especially wary of this. Do not use any middle man that makes the trade over instant messaging. Know the identity of the middle man. If its a professional service, make sure they have a written terms of service, and look over it.
- If they send you the money over Paypal, make sure the buyer includes a note that indicates they will not, for any reason, dispute the transaction. This is to avoid unwanted Paypal disputes, or charge backs. Do not use Paypal to send them a bill, make sure they are the ones who send the money directly to your account.
- List your product on Ebay or Amazon if the buyer is still hesitant on making the trade.
- Stay strict and professional. Do not give the buyer any leniency because they are polite.
