Why not ?

Google  (and other web search tools, like Bing!) will often filter results (see link below), especially for topics that might be considered illegal or offensive. The list of filtered words changes over time (see the example of Google removing 'bisexual' from its filter in 2012, below), but it is difficult because search engine companies do not make it clear when or what they are filtering when they filter search results.
