This is fine if the post is something insanely low effort.
But I do worry if this ends up being too aggressive.
One of the things that made reddit so awful is how over moderated it was.
I don't really take issue with dozens of posts by newbies asking the same basic question over and over. I used to be one and am occasionally back there again if I start a new hobby. Hopefully newcomers don't get pushed off by overly sensitive moderation.
It would be helpful if you could provide a hypothetical example of what is considered a "low effort" post.
