Your code is used for the "blur mode". "hide mode" eliminates spam
completely: one has to hover over the "hover to check" option to see
the beginning of the post title and if false positive or an
interesting commercial then click "not a spam" to exclude it from the
filtering. That's to accommodate two different desires expressed on
approx 50/50 basis: some want to eliminate the spam completely out of
view yet to be able to check each case for false positives; others are
more concerned about false positives so they want to make the spam
lesser distracting yet be able to see all filtered posts at once.
