Ok, Reason i am making this is because it is how i got scammed

.
First find a markee guy with a decent enough rep and maybe trustwho.
Now, Your hoping the guy is stupid[Like me
].
Step one:
Make a imposters aim, Pretty simple. replace i with l or so on.
Step two:
Message the person saying u are wanting to sell an account are u interested and also dont FORGET to say ur trustwho this makes them more comfortable and forget about asking you for some more info on urself. After this show them in game and all that jazz[Hoping u actually have an account, i would use a scammed one tbh]
Step Three:
Say you will take it for a little higher price than they say they have, they usually have more. They will usually offer that much if not just say ok ok ill take it. Once this is done, you have them send u the money.
Step Four:
Have them open a dispute saying all of your info, Tell them its so u know ur covered. Say when they open the dispute its cause u want this on record, tell them to say all this in it:
Name
Number
Also VERY important, Tell them to say "I traded a intangible item".
[If you get them to say this you are pretty much home free home]
Intangible means "An asset" Basically paypal cant refund anything that isn't something you can touch and feel.
Step Five:
Reply to the dispute saying " I acknowledge that this item is intangible"
Then, The dispute will be reviewed quickly and closed since the item is "intangible[The account]."
Step Six:
Enjoy!. Log off move to next victim.Do this alot before the word gets out. u should be able to get filthy rich ! 
You are practically safe from this if u get them to the the item was intangible.
Enjoy and have fun
