There are a few things that you should not Google, as they can be disturbing, graphic, or simply inappropriate. These include:
- illegal activity
- hate speech
If you are looking for something specific, it is probably best to use a more specific search engine, like Bing or DuckDuckGo, which can filter out some of this content. If you do end up on a site that is disturbing or graphic, remember that you can always close the tab or window, and that it is not worth exposing yourself to something that will upset you just to satisfy curiosity.
