It's using zaps to farm engagement and advertise. Right now, nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n is zapping people (sending lightning sats) for discussions around their products.

And it's working, my nostr feed is full of liquid bitcoin, jade, and green wallet discussions.

No need to apologize, glad you're asking questions! Everyone was new once!
