Proof that it's their Discord:
Explanation of the trade: I've seen him numerous times have sales for his webshop. Today and dm'd me and posted in his own discord server the 60% discount of all accounts in their webshop. I should known it was too good to be true. I purchased a MM2/demonic gorilla account for $40 (originally $100 before discount). I go to log into it via not only on the official RS website but also on outlook. I couldn't log into it on either. I then go to post about it in his discord server, which is now deleted. I then go to DM him and he has changed it to friends only. I should have checked the scam reports on sythe as I had seen a lengthy scam report which was in his favor but still decided to scam..? I was skeptical that this was very fishy so I'm glad I only did $40 and not more.

How they scammed: Didn't deliver the account I purchased with proper information
