I am suggesting building on this suggestion and this one, to add a confirmation "user must click through" message stating to the effect of what is said in this answer
Why are upvotes and downvotes here different?
Voting here works a bit differently from other Stack Exchange sites. On Meta Stack Overflow, voting is used to express agreement or disagreement, not to point out a lack of quality or helpfulness. Please don't be concerned if you receive downvotes – members of the community may simply disagree with your bug, feature request, support question, or the nature of the discussion.
This would be for all meta.whatever sites.
I know this is in the FAQ. But I find myself so often posting things like this on meta.workplace frequently, so obviously people are not finding this ahead of time.
Users would have to click acknowledgement to having read this message before being able to make their first meta post.
