#shadowbanning is nostr possible at mega app level and circle of WoT scale - essentially new npubs gets less exposure what they post. Certain app can push certain npubs only not based on content of notes That's push side
it also largely depends PULL type skill of end user if they search keywords correctly. key is most of indexing NIP-50 are ignored due to many reasons. what is not possible other controlled/paid social gossip platform is TAG / INDEX / SEARCH openly but that need user skill + choice - nothing timeline feed when someone has no ability or interestest to CHOOSE own content. having said that - 90% transmitted over relay are REALTIME - if anyone not looking livefeed they unlike see the note unless search or visit npub post or it pops by coincidence. hence SEARCH + keyword most important tools since nobody can browsing 24/7 - WoT n Npub based ratings useless
to promote any note - somebody sometime can always GOOD note. most of my notes not good enough doesnot mean i never post good useful one. same true for fresh npub. judging a note no. of reactions can be futile. must some way "rate a note" based on consensus - that can pushed much more - e.g. quote of report maybe. usually global feed on an OPEN relay is most unbiased source once alert bots/spam is filtered. i like certain alert bots i look them ONDEMAND only.

indexing, archiving, pay-per-search/view old notes can be good service. excluding GM / GN /PV
