I understand @Garden Gnome Publications - personally I think it is fortunate The Movie Reviews niche is owned by Rosemary. She's not going to leave the project if her niche becomes so gummed up that everyone unfollows it and her revenue from it tanks. She's far more invested than just through that niche. Other niche owners might very well leave subjected to the same torrent of spam.
Narrators have worked hard to build the followings they have so far - the hardest push is the initial one. All subsequent pushes benefit from the existing momentum. Niche owners have completed the first push for many of their niches - but some of them are going to feel seriously let down and feel their efforts were not respected. Not only is there no measure in place against spam of this sort, but the Community spoke almost of one voice, on the insufficiency of limiting posts to 10 per day. That was never going to solve the problem - I still can't wrap my head around why anyone thought it would.
Some Narrators proposed a limit of 3, and many preferred a limit of 1, with barriers to upping that limit, through staking, paying NRVE, and/or being above low rep. These suggestions were left unanswered (as is the case for the vast majority of ideas the Community works to present to the Company. And they were, of course, not implemented.
What is fascinating to me, are the inferences we can draw from the Company rejecting the 1 post per day limit, with a pathway to increasing that limit. The effects of this measure would be threefold, and all of those effects are positive, although a couple of them might be controversial for the Company, and interestingly so.
1) Spam would be reduced tenfold. Literally. Everyone wants that, unless the Company is shortsighted enough to enjoy the boost in active users represented by the many dummy spam accounts being created
2) Staking and/or a NRVE payment to unlock an additional post or two per day would increase value of NRVE
3) Limited to one post per day, Narrators would focus on quality more. It would reduce the volume of posts hitting the platform, but increase their quality. Leading me to wonder whether the Company even cares about quality, and actually prefers volume because it feels its algorithms are successful at hiding the garbage (they're not). I went to the trouble to ask the Community months ago how they used the feeds, and almost 100% of responses said they focused on the Discover Recent feed - which is a feed that is not influenced by algorithms and shows EVERYTHING. None of these efforts and information result in responses from the Team, and none of them seem to lead to action.
From where I stand, these anti spam measures would be a real boon for Narrative in the three ways noted.
