Does this just create a gerontocracy where old members gatekeep forever?
I don’t think it determines a gerontocracy (do people really care about upvotes?) and I don’t think it solves the problem you’re worried about either.
How do you handle the first 30 days when no one has much weight?
You show upvotes as a %, so if a post has +.01/-0 it’s still 100% upvoted.
Would this actually prevent the decay, or just slow it down? Is there a simpler/better mechanism I’m missing?
In your scenario, “hardcore” members leave because the signal/noise ratio is so low that the community is not worth following anymore.
That has nothing to do with upvotes and all to do with mods failing to take down meme posts (assuming members don’t like memes).
A community is its mods: if they allow low-effort posts (without meaning to) they are not doing their job properly, and that’s probably due to the job being too difficult and/or requiring too much effort.
You could look into allowing older members to help moderate, or maybe into allowing mods to flag “trusted” users whose downvotes (possibly unbeknown to the users themself) will result in posts being taken down “for review”, or otherwise figure out some other way to help mods out, both when making up the rules (that too takes a lot of effort!) and when moderating posts/comments.
A lemmy/reddit-style community is its mods. Think of how to help them be effective.


Nice! Now do the same for ipv6 :p
Any way to determine/estimate if the black squares are unused blocks (“give them back!”) or just not responding to pings?
