Oh my archnemesis :)

If there were, there wouldn't be any way for you to get them back. Your items have probably been fenced, laundered, and resold several times over by now before ending up in another innocent trader's backpack. And I know you may not see it this way, but you have no right to demand your items back from whoever has them now. Just as another scam victim would have no right to demand items from you claiming you got them from a scammer.

3 years of experience chasing scammers around tells me that Youtuber has nothing to do with it, and a scammer is just copying their actual profile to look legit/famous and steal from more people, while blaming the innocent streamer.

Sorry, your OP specifically asked about where your items went, which is exactly the kind of thing csgo.exchange would be used for, so I thought you wanted to track down their new owner. You might find his main account if you're lucky, I've seen it happen a few times. You might also end up chasing down and harassing an innocent person in a witch hunt though, so I don't advise it. Plus, even if you do find him, it won't make him give your stuff back or compensate you I am sorry you got scammed, but you should probably try to learn from this and move on instead of stalking the scammer across multiple accounts for revenge.

If it's on his profile, then it's almost definitely not him. Scammers point to other people's Twitch/YouTube claiming to be that person all the time. Impersonation victims get enough hate as it is, please don't add to it.
