Ok, so I have been scammed soo many time from MarkeeDragon and had about 3 accounts with real my info banned so I don't the same to happen to you.
Always, when you are trading accounts or selling/buying, check this forum just to make sure he isn't a scammer.

Always look if they are TWV(Trust Who Verified), which means that they've payed an extra 5$ to get this rank! Also, look for positive rep and many post people and even if they look really legit, be aware that they could just have had tons of friends who are scammers also and gave them positive feedback. Never go first if you do decide to trade with a low post/rep user on there and always get to know the person. If they are too anxious to trade, just drop them, theres probably 10 other people who just haven't messaged you yet! Also if powerleveling or trading accounts, get a middle man! Make sure he is very trusted and trade will go by really smoothly. Trust me!I really don't want the same to happen that happened to me. Be very careful, like 60% of that site is all scammers.
