In the last few months, there have been inquiries that are obviously spam, in the messages the alleged guests send their e-mail addresses and request direct contact, which obviously leads to some fraudulent scheme. Please take note of this phenomenon, there are several inquiries a day that are conceived in this way.
I do not get this type of message frequently.
However when I receive some of this kind, I usually denounce by clicking on the small flag icon that appear on the right side of the message.
It is really annoying to receive this type of message, so we have to denounce to help Airbnb to ban bad users and spammers that infiltrate in the platform.
