AirBnB were fined for having non-licensed properties on their website. It is not permitted to advertise a property in the Valencia region without displaying the License number. Last time I looked (and we don't use them ourselves so it was a while ago) AirBnB were asking for License numbers and verifying them before accepting adverts for our region, as do reputable websites. As regional regulations do vary it is possible they are accepting adverts from other regions when the License is in progress as other regions do permit that, but it is a national law that governs the need for having a License, regional laws deal with the detail of criteria to be met for the License and process of application.
It is still illegal to rent out a property for holiday/leisure purposes to anyone without a Tourist License and without paying due tax on that rental income. Also need to comply with the requirement to register all paying guests, which you cannot do without a License. Non-compliance with any of those things can result in a fine. You said in your post to RENT it through AirBnB without a License and you said the RENT it to friends and family or let them stay for free - so, with all due respect, you did suggest they do something illegal.
I have given my suggestions for doing what they can to legally prevent future occupation by squatters in previous comments as requested in the original post.
