Thanks. We're working on ways to secure the capital for things like retaining a lawyer. It's not the fault of the space itself; our business model hasn't been fully executed.
As to it being an arms race, I'm not sure the techniques to filter content are really competing against anything. Sure, it seems like there will always be more sites to ban, but its not like adblocking, where the tricks are getting more sophisticated over time.
Also, I like (most of) my users! We've had some spam issues in the past where users created minor headaches, but this was a first.
