i’m confused - isn’t that a Like notification? why would you want all your likes to be votes?
perhaps you want the Discourse Post Voting plugin, although i have no idea what the notifications for votes looks like?
can you provide more information on what you are trying to accomplish? from your post, it sounds like you just want people to vote on your posts in a topic? if you want people to vote on your topics, you should then use the Discourse Topic Voting plugin.
