Rs3hot Blackmailer and Scammer

Explanation of the trade: They offered to buy my 07 account. It was going to be paid through paypal.
How they scammed: So long story short, they gave me a few offers and I accepted the last one, we went through the process of giving them control of the account. After they had control of the account I asked to be paid. At this moment they inform me that I will be paid 30% now and the rest in 20 days. So it took a bit of time to negotiate the price and get the accounts setup. After seeing that it would take that long to be paid in full I request to back out of the offer and have my account back. They did not inform me before I gave them access that I wouldn't be paid in full right after the trade. A lot of arguing ensues and then they say that I will have to accept their offer or else I will have to pay 10$ for the time. Essentially blackmailing me into accepting their offer which I did not want to do. The whole conversation is huge so I'm posting a few screenshots, I can post the whole conversation on request.

Sorry I don't see anything worthy of a scam report here. Welcome to the hell that is account sales.
