Well, I was amazed by the price of the product on their site, so I ordered it using PayPal in no time and got the email everyone mentioned. You need to give your ID, your photo with you holding the ID and passport... there is no way in hell I'd send it! So I used the form they sent me to fill in, typed in ONLY the data from my PayPal account and gave my signature, no IDs, no photos, but informed in the email with the attached form, that either they'll process my order or I request an immediate refund. Got the transaction accepted in mere 5 seconds (literally, I didn't even manage to switch browser tabs when I got the email).
So yeah, fight for your privacy.
