Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
