Voted in poll.
I think only allowing community members to vote is a reasonable solution. This is similar to political parties and having primaries, so it's not a radical idea.
If one is not invested in a community and not contributing (in whatever ways), just stay quiet and observe on the sidelines.
If one is invested, then by all means take the time to subscribe and truly help build a community with your engagement (even if just by silent voting).
I'm confident there will be some known trolls and haters who simply like to downvote for the fun of it and they will spitefully subscribe to every imaginable community to demonstrate their "right to downvote". 😂 Bless them...
