scammed by MM imposter and someone who tried to buy 350m

Scammer's profile link: I didnt get a sythe profile from him

Amount scammed: 350m

Discord ID + Unique Discord ID: Benjamin McCain#1794 UID: 793241216262864908 was the person trying to buy the 350m
Alibabas#2087 UID: 783620412520529940 was the fake MM he brought in

Proof that it's their Discord: unfortunately i never got a hold of their sythe profile..

Explanation of the trade: So the plan was to sell Benjamin 350m for BTC
we agreed to have a middle man facilitate the trade me choosing Alibabas as the MM.
I spoke to the actual Alibabas to start the trade and made a group chat where Benjamin kept asking for a sythe PM, where alibabas stated he will do so after we fill out and post the template, so he acted sketched out claiming hed already been scammed and wanted a sythe PM first before anything. He then proceeded to leave the group chat, ALibabas (the real one) then went on to create a second GC where again, benjamin, claims he wants a sythe PM first and leaves because he doesn't want to get scammed again. Then another group chat is created, this time by the fake Alibabas ( me thinking it was the real Alibabas that made another GC) where the fake alibabas is now saying he replied to the guys PM and to check and they both agree that they're good to start the trade. This being the first time ive had a MM facilitate a trade i didnt expect to get scammed like this and since ive dealt with Alibabas many times before (and i thought it was the real one) was ready to start the trade, i then proceeded to trade the 350m to the fake alibabas where everything still seemed legit, then benjamin started asking if i have more which i replied no to and he kept going up in price for more GP, thats when i realized it was a fake alibabas i traded with

How they scammed: used a fake MM
