I have aways been against any type of “negative vote” kind of thing.
Not that being called out for being wrong is a bad thing, nor is constructive criticism on how something “right” could be improved upon. But a simple Down without further explanation seems pointless and likely detrimental.
It’s enough of a concern that even Likes could be gamed to falsely “elevate”, but I can see where it could be useful for building a Community.
Having a Dislike could be gamed to falsely “demote” and IMHO would be destructive to a Community feel.
I would rather have a community that supports each other than one that bashes each other.
eg, I’m a newbie and find that all my new posts are being Downed. I don’t feel welcome that’s for certain.
I’m a newbie and all my new posts seem to be getting ignored. I may not feel very welcomed, but I can live with it.
