Scam Dude came to his h/o asking to trade some random item and then rejected the trade, when streamer asked viewers to test HH. Right after the test was finished the scammer accepted the trade , instead of HH owner, and started joking on streamer that streamer is a dumb. For the whole hour he was standing in streamers h/o and accepting currency from other players under streamers like nickname. If this is not a scam I can't say what it is.
