Things to think about when trading

?It is not safe to buy an account instantly only because the seller has the confirmation key. Since the hacker could simply order a new one the day after you activated yours and take back the account since the keys are sent through the real mail system to the address used on the account, which his his. It ALWAYS takes 30 days to change the registration on an account, having a confirmation key or recovery key doesn't make it go any faster.
Make sure the buyer/seller sends you an e-mail saying "The trade went smooth, I received XXX amount of cash/items/character, and paid away XXX. By having a email from the buyer/seller stating that everything went good, it is much harder for the buyer/seller to scam you.

Use the search function on the top right of the forums, or ask around to other people to see what his trading history is like. If you don't feel like he is a trusted member, try asking for a middleman. Tons of people have previous middleman experience and know all the proper steps to make a trade safe and get it finalized.

If the person you are attempting to is bragging about making tons of safe trades, make sure you get in contact with one of the members he previously made a trade with. Make sure to check if they are friends before you do, it is possible that they are just backing each other up so they can get a trade done without really being a trusted trader. (Which could be unsafe)

Remember that a confkey is valid for 60 days. The activation order doesn't matter when buying multiple keys. Which means, if you order 1, and 2 days later order another, and decides to activate the first one that arrived. The second one is still valid, and the other way around. Due to that, the account isn't safe from hacks untill 60 days after the purschase. You buy it (30 days), + another 60 days, as the seller could as well have ordered a new key to his adress on day 29.

Don't forget that a confirmation key is valid for 60 days. The order in which the confirmation keys are activated doesn't matter if you have multiple. So if you ordered 2 keys and decide to activate the one that arrived first, the second one is still valid and can still be used. Because that is possible, the account won't be safe from being taken back until 60 days after the purchase has passed.
