For me this page redirects me to airbnb.co.uk and the relevant portion of the agreement (Payment Authorizations) says:
> In addition to any amount due as outlined above, if there are delinquent amounts or chargebacks associated with your Payment Method, you may be charged fees that are incidental to our collection of these delinquent amounts and chargebacks. Such fees or charges may include collection fees, convenience fees or other third-party charges.
I'd be interested to see how the wording varies between jurisdictions.
