Possibly, I just think it would be better if we had the option to essentially filter content out from people using it. I would be willing to bet that I'd end up being annoyed far more often than not. Friction isn't a small thing. It matters and removing it will only increase the problems. That's basic logic in my mind. Harassment isn't not going to get worse when it's far easier to spin up a new identity.

Yes, it's possible already but we have to consider the consequences of making it easier. Filters are the way forward in my opinion. Like filtering out new npubs, for example.
