Scammer's profile link: tr0yfkdya
Explanation of the trade: was looking to buy 100m osrs gp from him, i went first paying $20 for the first 20m but after payment, he went offline on me, possibly blocked me and pretended that we never dealt on his thread. he changed his skype contact email that was on his thread possibly pretending as if we maybe added an imposter.
How they scammed: ^
Proof that it's their Skype:
as mentioned.. he changed his email on his thread so theres no exact proof, on his thread, he now has this.

but his original email that i added was Duradelhf@gmail.com and if you go through the reply posts, many others have vouched that it was originally Duradelhf@gmail.com
now if you search his skype with that email, it no longer comes up.

Even if he changes his post, mods can just view history.

You're correct and I have banned him.

Sorry for your loss. To be safe just use a trusted MM.
