I think Nostr will be much better when there is an image filter for NSFW items, I can’t browse hashtags for all the crap that gets posted. Then an algorithm that I can adjust. 

 Damus allows you to blur images now. 
So you want algos?  Got it✅ 

 Need a paid premium version, filter to only paid profiles, probably get rid of a lot of spam bots. Nice way for developers to make coin too.
