@Sunni23 Contact Airbnb and tell them that the husband of the person whose account they deleted and whose booking they cancelled due to quality assurance information is now trying to get around it by opening another account and sending another request. Ask customer service to please cancel the request and prevent them from sending you more requests, as you feel unsafe.
The account was likely flagged because their payment method failed, was found to be fraudulent, or the guest was reported for trashing someone's house, throwing a party, or other violations.
