I've lost over 50K DOGE on this shit and another ~$500 on other balances.

The site is offline at this moment (DNS mismatch) and the Discord was fakely closed by KD scammer to hide their shit. If you go there with BetterDiscord you can see the #staff channel is pretty active.

Moreover, @tillkoeln was last seen recently on Telegram.

It doesn't take much social engineering on Google to find that tillkoeln is the pseudonym of Till Schmitz from Köln/koeln (Cologne), Germany. He supposedly studies on Tilburg University. If it's him, he's the dumbest scammer I ever seen to expose too much about himself before scamming people lol.
