I know computers and algorithms are funny but clearly, when you search for [wank] in Google Images and set the SafeSearch filter to moderate, no or little pornographic or nude content is coming up.

If the lesser version of SafeSearch is blocking it, what is wrong with the stricter version of the filter?

Of course, I blurred out the nude ones. Keep in mind, there are plenty more when you scroll down.

Like I said, I guess this is just a weird quirk in Google Images SafeSearch algorithm and Google will fix it. But just weird nevertheless.
