How do you mean? Presuming a person give consent by default and making it public and accesible without warning and explicit consent is the same as ... well not asking consent . Same logic as nude texting and flashing.

You give consent to be served search results that match best fit with some content filtering based on best intentions.

Implied is an understanding that despite best intentions of the search provider, stuff may slip through.

This is vastly different than being flashed.

My comment was more general than search results. All the major search engines as you said make best effort to exclude nsfw content by default and I have no problem against that.
