@Yan-Yan0 If this is one of those messages where they say they'll pay for the stay but not actually come, and you'll split the profits, it's a stolen credit card scam. Just reply to the Inquiry "I don't deal with scammers" and report it to Airbnb. Absolutely do not communicate with them off-platform. There is a flag to click on by the messages to report, and would be a good idea to contact Airbnb directly to report, as well.
