The other difference is that Google searches the mainstream Internet whereas Grams searches the Dark Net, which might be described as the Internet's secret evil twin — though not particularly well-known in mainstream circles, it's been around since the World Wide Web was still ARPANET, and you can't even log on to the Dark Net unless your computer's outfitted with anonymizing software.

Once you're on the Dark Net it's still hard to find anything, since the web addresses change all the time (if you're running an illegal market, you don't want to stay in one place for too long). Hence, Grams the search engine.

When the developer discussed Grams on his (or her?) blog, the sample screenshot showed search results for MDMA, the illegal drug also known as ecstasy. That was a clever PR move on behalf of Grams' developer — after all, though MDMA is undeniably illegal under U.S. law, there are many who believe “Taking MDMA (or other illicit drugs) is a victimless crime, and should therefore be legal.” From that perspective, a presumably secret search engine like Grams strikes a blow for liberty, in the “help evade unjust laws” sense of the word.

Problem is that apparently, Grams can also be used to commit crimes with genuine victims — such as, searching for stolen credit card numbers to commit identity theft.

Media outlets ranging from SFGate to Ars Technica listed stolen card numbers among the types of items Grams can help you find.

That said, it's not certain if Grams will last, as it might be illegal in two different ways: one, for helping to facilitate illegal activities and two, for using a style and color scheme that's an obvious ripoff of Google's.
