I’ve thought of doing something similar, and think, while the federated spam is hard to deal with, signup spam is manageable if you somehow restrict signups to the actual community you want to support. Open signup on the web is a nightmare.
For a city, an interesting idea might be to only allow signups on a dedicated, physical wifi AP placed somewhere strategic in your city. People would literally have to go to a physical location to sign up. Piggy-backing on a library system would be another option if you could somehow get them to buy-in.
