How do you define a "Bitcoin business"?

What constitutes "spam" on nostr?

Would I need to be selling sas or intangibles to be cool enough to hang?

I feel like a community focused on money(Bitcoin) should be open to supporting each others businesses. I don't really care to be a "influencer". I'm never going to be able to live off the tips for my whitty posts or sexy pics. I am a mobile welder in the Tampa Bay area. I accept Bitcoin straight to my own node/ keys. Is there a place for me on nostr? Will I get booted from relays if I "shill" my business?
