fwiw i think that karma could be useful in the future; but lemmy lacks the resources to implement it w/o it getting abused.
so i think it makes sense to wait for the those with the finances to pay for the development teams to figure it out and, once they do, we can copy/paste their idea(s) into implementing something like this that is viable and maintainable for lemmy.
The platform is mostly on autopilot; it can limp along for a long time
