I agree that you are saying "Also Lengthy posts of 400 words are not always quality posts." I made a point about that in the post above.
That's fine, it's up to them to upvote whatever they want. I'm just saying 200 words and up is plenty to get non spammy Good Quality Posts, that's all. Thanks for replying back @dblogger .👍 I checked out your link.
