"Illegal" is relative in this case. The law isn't a set of divine rules to live by (you're probably breaking a few laws by accident every day), it's more of a correction mechanism for abuse. That, and every country has weird quirky laws on certain matters. Just use common sense.
That said, you should be careful with your ID. But, I personally wouldn't mind verifying my ID with Airbnb (last I checked, they used specific verification software)
