This would prevent karma gain from “interest” on old comments
If you want to reward having a long history of comments, you could prohibit only downvoting of old comments.
it wouldn’t prevent ongoing retributive downvoting
I doubt you could algorithmically distinguish between downvoting a horticulture post because of disagreements about horticulture and downvoting a horticulture post because of disagreements about some other topic.
But I suspect voting rate limiters should keep the problem in check.
