I’ve been so used to judging a post just by its popularity on reddit, but it’s actually so much more useful to have an idea of the downvote ratio. I’m glad we have that here.
It was a scandal when it disappeared from YouTube, but I didn’t realize it was missing from Reddit too for much longer!
Enabling downvotes is a server setting so yes,the admin can disable that.
And afaik there’s currently no way to migrate your profile to another server, you’ll have to make a new one.
