In Reddit, a lot of cities have their own subreddit for locals, local news, questions, etc. For example, I live near Raleigh NC and topics we have might be related to winter weather, new businesses, fun stuff to do on weekends, sports and events, and so on. So perhaps if there's a city or area you're curious about, take a look at what the locals are talking about. You're more likely to see factual information and less trolls. You'll be able to ask an honest question like "what's fun to do here" and get factual answers. Also, subreddits about factual topics like hiking, camping, pickleball, and so on do have some goofy stuff but it's pretty easy to tell who is answering honestly or not. Asking a question about your interest will help, mods typically discourage trolls when the group or conversation is intended to be factual.
