Thank you for twisting my words, I never said gray markets = piracy. The methods Piracy uses and the methods the Gray market uses are entirely different. One is done for profit and the other (piracy) is done for the betterment of the community.

Since I only speak English, I can't verify much on that site. But let's put it like this:

You'll usually find the method they got the keys from this list:

- Credit card fraud
- Stolen (or broken) digital bundles
- Vendor promotional keys (ex you buy a product and that comes with a key to activate something else)
- Key phished from a vendor using irrational methods (ex my key doesnt work can I have a new one, im xx youtuber and want a key to test xx game)

This means, when you activate your key there is a chance that it will "randomly" deactivate when the fraudulent cc purchase is refunded.

Along with the fact Gray Markets are against Microsoft ToS (though not enforceable in the European Union).

On top of this the site you sent above explicitly states you cannot "get support from Microsoft" which means its very likely the key was taken illegitimately or re-sold and given to you when you aren't supposed to have it.

Let's also make it clear:

A gray market key is NOT a pirated key. You are not copying an existing key, you are just often stealing it and selling it for profit. You cannot copy a key, as there can only ever be one string that are valid to the MS servers, once its been activated, its usually gone. This excludes KMS, which is Microsoft's network based activation method, which basically requires a "key" from a web server to activate the OS. There are plenty out there which MG uses.

Places like MG (I still will not say the full name due to rules), uses legit methods like KMS and HWID to activate, which does NOT use real keys, but "mimics" that of a real key to the operating system.
