These suggestions are modified version of limited word comments.
Simple Suggestion
This is quite a simple suggestion and can stop a minority of the spam all over the place.
Ok you always see some people posting blank words as their comments. Also, comments that are wayyyyyy too long it turn out blanks. So what if their was a message if you posted a blank comment and stopped your from posting nothing. Also it can give yo ua message when your post is too long and will turn out blank.
Extended
Here is an extended version, if this won't work, then it will just be the idea right above.
Ok so if you posted a comment less than 7 words it will give you a warning and will tell you to review the Rules & Guidelines before posting.
