I have a hard time to figure out how i can actually use profilestr. It looks nice, interesting statistic (apparantly 4.000 daily active users on nostr) and some filters for the statistics. i also learnt that my trust score is 70.
But to filter out like you said it would be nice to be able to log-in, apply the filters and then bulk-mute imposters, bulk-unfollow bots, etc.
I can see that there is a lot of love in how it was built. It really looks beautiful.
