curiosity value > fractional bitcoin value

It's also validates the scam for other users. When they see BTC being sent they are more likely to think it is genuine. I can see sending dust to track the coins but other than that it's a damn foolish idea.

I imagine there’s only a small overlap between users that know how to track transactions, and those that would fall for this.

I'm actually kind of interested in exactly what sort of overlap that would be.

You can't stop stupid.

Curiosity, mostly. This was very soon after the tweet was posted, and it was less than a dollar.
