I think there are around 500 real people on here over the course of a week. The nature of nostr is that it can be used for anonymity, so that precludes using your real photo or disclosing your location, job or social circle. The purpose of NIP-05, zaps and bookmarks is to convey your credibility. Filling out a profile is more for window dressing IMO. My identity is well established on stacker.news/Brunswick and I've been on nostr long enough to look through my history and see if I'm a real person and if I'm pro-homo, pro-war, prostate or whatever. Nostr isn't twirker or zuckface, but I agree building a list of people you want to follow is hard. My rule of thumb is if a person consistently crosses the line with me by talking about useless shit, they get unfollowed. If they spam my comments with ads, they get blocked.
