VK users have shared their opinions on the resource, with many rating it highly:
Since "4000 Essential English Words" is a well-known six-volume series originally authored by Paul Nation and published by Compass Publishing (and widely distributed on platforms like VK), I have generated a formal regarding the series.
Compass Publishing has sent DMCA notices to some VK groups, but VK’s location (Russia) and limited international copyright enforcement mean that removed files reappear within hours. Some groups now use cryptic filenames like “4k_words_B1.zip” or require users to join closed “educational purpose only” groups.
Many VK PDFs are not the official digital editions. They are often grainy scans of used books. You will find handwritten notes in the margins from a previous owner, blurred images, and sometimes missing pages.
