By default, Lemmy allows downvotes globally. However, when a server disables downvoting, it is similar to using a feature that is usually reserved for enterprises and very small, non-federated communities.
If a user prefer to not see downvotes, they can disable it by his favourite client settings, but the rest of the community should not miss this functionality for the pleasure of few users.
I do not care enough, because here on lemmy.world it isn’t a thing. But I see you’re from lemmynsfw. I vaguely remember a thread where the disabling of downvotes was discussed and to this day I do not understand why people are afraid of downvotes on their wanking material.
They disabled downvotes because they want to encourage people to post porn of themselves not just to repost stuff. Getting downvoted for posting your own work isn’t encouraging and essentially kills communities before they even start.
This actually makes sense. Thanks.
Downvotes discourage reposts more than anything.
Reposting is not a problem, it’s an NSFW server, nobody will downvote repeated content. What was getting down voted were dudes and chubby women showing off.
I cannot affirm with certainty there is correlation, but the main page is far more diverse in people and content since the removal of the downvote, and constant reposting is not a thing I see (at least for now).
