Crank scrapers or plate...?

Tell me how you really feel, dont hold back! Whats innacurate in my post. Whats the guys application? IJ isnt forcing anyone to buy anything, where is that from? The oil level in the pan at the full mark is about 2" below the crank throw, even more when its running. Chime in, tell us where I am wrong. If every motor could use a scraper to its benefit, why wouldn't every motor have 'em? Stamped steel isnt that expensive.
