Maybe this will answer your questions:
Still in business, just don't pay attention to the numbers and dates on the covers. Maly Modelarz was, and is notorious for lengthy delays in publishing new issues. They do recycle older designs, but hey are redrawn and recolored so there is an added value there.
Here is the one and only official web page
Ma?y Modelarz
All vendors offering printed copies of the models are legitimate.
All pages where you can find electronic single issues of Maly are pirate sites.
The only legal way to obtain electronic compilations of old issues of Maly is to purchase them on CD (one year per CD) - piotter provided the link.
