Scammer's profile link: N/A - user contacted me saying he saw my post on Sythe, did not leave a PM
Amount scammed: 65m OSRS
Discord ID + Unique Discord ID: KINGPIN77#4439 / 409744111411658753
Proof that it's their Discord: Screen capture - 3e6dbefebac53813d958f043bcffdfba - Gyazo
Explanation of the trade: I was purchasing SPK gold through out the day from this user, we had done 4 trades prior to this, first trade was 30m osrs for 500b SPK, then a further 115m for a further 2.1T - these trades went perfectly fine. He then said he had collected more and had 1.8T, i said i would take 1T from him. Given how the previous trades had gone i trusted the user and went first again with the full amount.
How they scammed: Took the GP and then blocked me on Discord, also left any mutual servers we were in.

Hope the above is sufficient evidence to show the user scamming.
