What is Z-lib?
Z-lib.sk is in our scam category. This label is used for domains linked to deceptive offers, non-fulfillment after payment, or data collection under false pretenses.
What users usually see: copied branding, fake trust badges, edited reviews, and checkout pressure (timers, "last items", "verify payment"). These signals are easy to fake and should not be treated as proof of legitimacy.

Signs You're Dealing With an Online Scam
Scammers have devised new ways to deceive users, and what was relevant ten years ago may not be applicable today. In this post, we have compiled the most current types of online scams.
Z-lib.sk is affiliated with the Russian Federation, a nation that initiated a military attack, thus committing a crime against humanity in the form of war against Ukraine for the past 3 years. Our company, Gridinsoft, is based in Ukraine.
The ongoing war has resulted in tragic losses, with our children, parents, and friends facing daily hardships due to the deliberate actions of the Russian military. Homes are being destroyed, and millions of our fellow citizens have been forced to leave their residences.
This is not a political statement but rather a heartfelt plea. We earnestly ask that you refrain from utilizing services provided by websites from Russia. We appeal to your sense of humanity—please avoid purchasing their products or engaging in business transactions with them.
It is critical to recognize that each individual's choices contribute to the financial resources available to the Russian Federation, which directly impacts its ability to sustain this war. Your conscientious decisions can play a role in promoting peace and stability in Ukraine.
