1. Yes, there are hello bots, and there are real people welcoming boobies to nostr.
2. Yes, but i dont there' s a specific NIP. nostr:nprofile1qqsyvrp9u6p0mfur9dfdru3d853tx9mdjuhkphxuxgfwmryja7zsvhqpz9mhxue69uhkummnw3ezuamfdejj7qgswaehxw309ahx7um5wghx6mmd9uq3wamnwvaz7tmkd96x7u3wdehhxarjxyhxxmmd9ukfdvuv created amethyst, so he'd be able to give you a better answer.
3. Laser eyes is Bitcoin culture. It signifies staying "laser focused" on stacking sats... etc.
4. Yes, long form are just longer notes but with their own nip. There are apps specifically for long form. They way uses aren't clogging up the fees with absurdly long notes. Think of it like writing a blog, instead of a note.
5. Kinda. If your video is pre-recorded and is under 50mbs, you can upload for free on most nostr/blossom servers. There are also cdn type services like catbox.moe where you can upload to about 200mbs. However, these services usually keep you filled for about 30days. You can spin up your blossom server, and change the keep-time to whatever you want, and share the link to that file on nostr. Then, there's plebs.app, which is like nostr YouTube. The 30days rules still apply, but your videos are spread across multiple blossom servers, and you're still able to add a personal blossom (if you have one).
If you're referring to live streaming you may have to pay. However, zap.stream has a free tier that you'd point OBS toward. And again, you can spin up your open solution faaairly easily (kinda).
