The number of comments is actually the number if edits. So "20" might actually be one comment that was heavily edited by its maker. A comment that violates T:SPOIL will get deleted, and some people delete off-topic comments as well.

Usually, though, page blanking is not a good thing, and is a form of vandalism, I believe...

Examples? The page history should answer your question...
