A few years back I saw a mention of something I 1) didn't believe and 2) had to check.
It said with safe search using an image search for British, American, European, or African brought forth a load of flags, politicians, and the like but a search for Asian just came up with porn. I tried and it did. I retried recently and again just now and it doesn't any more so clearly Google must have fiddled it to make sure that doesn't happen any more.
