Other than that, I can appreciate your reasons for not wanting to follow a hashtag if it will have NSFW content sprinkled through it. I think you will find that as Nostr grows, it will be damn near impossible to find a hashtag where that is not the case unless you can filter the posts within it so that it doesn't show anyone and everyone who slaps that tag on their post.

Again, nothing personal. I can see that its not going to work for me and probably many other other people. now that I've called attention to it, there are others wanting to prove some kind of point by intentionally polluting the hashtag with trolling photos and I simply don't have the time in my life to include people that do so intentionally. One can play cat and mouse with blocking, but it's simpler to bow out of the entire concept of hashtags until they fix it. It's a shame because I had hope for its potential.
