Here are two nice disclaimers that I came across, and which certainly apply here:
Caveats aside, we hope that this collection will facilitate your flying, and invite you to send along any suggestions, corrections, and new data to John Leibacher ( john.leibacher.wstx@gmail.com ) Fly safely!
The airspace for Poland is published at goo.gl/cCWr5V

The data are not certified and must not be used for primary navigation or flight planning.
Never rely on the data. Use at your own risk!
