Even with safesearch on you can find some strange things. I tried to find a picture of Sonic the Hedgehog for an assainment project for designing a games magazine on Adobe InDesgin. First picture that came up? Sonic bumming Tails! Searching for most things anime or games related leads to hentai though! Even The Simpsons aren't safe!

SPOILER!!:
For the sake of your mentality, do not search "Lemon Party" with safesearch off. One of my friends did and what came up was... kind of... worrying...
