Answered: No downvotes[ Free]

That’s a really helpful idea!

If anyone wants to disable downvotes without a plugin, you can also do it by editing your qa-config.php file:

This way, no normal user can downvote anymore — only admins (if you want).
But your plugin sounds cleaner and easier to manage, especially for public communities.

Could you please share the GitHub link again? The one in your post seems to be missing.
