Generally speaking, websites already carry embedded tags that can be used to filter them, good search engine placement relies on a website being associated with keywords that are appropriate to it. The main RG site contains the following embedded in all the pages...
Code: Select all
<meta name="keyword" content="Retro Games, Commodore, Sega, Nintendo, Atari, Sinclair, Neo-geo, Sony, Coin-Op, Mobile, retro gamer, retrogamer, classic games, reviews, magazine">
...because it wants to rank highly in searches for those words (i've just noticed... no Amstrad or Microsoft in that list!) A porn site will want association with the kinds of words people type into Google whilst looking for
porn so those same tags can be used for blocking purposes. There are also bodies to register a website with if it's adult in nature (and that isn't limited to pornography of course) and the home filtering software's manufacturers have their own blacklists which are constantly updated.
It doesn't stop everything
getting through, but the same is true of life in general, kids will still find discarded porn in the park or wherever, borrow video games from friends with adult content (even if you're a good parent and prevent your kids playing things the BBFC have said they shouldn't, you're to some degree at the mercy of parents who aren't as cautious) or sneakily watch violent post-watershed movies when they're believed to be asleep.
