I don't think there's anything fair about this. I don't like the idea of a US company censoring information from me in this way. Because now I'm really curious as to what else is being censored/flagged out.
I think the more surprising thing is that it only effects the Image search results, and not the web search results.
I checked the Video results, and Videos also appear blocked.
It's possible that Image and Video search utilize the same word-filter list, and for some reason web-searches use a different list.
Blanking out image results for a specific search string is a technical issue? This goes a little bit beyond assuming incompetence.
