Yes, I've had these sorts of enquiries before too, but 25 in the space of a few months seems like a lot. I wonder if there is something specific about your listing/s that are attracting these scammers.
You are right not to trust the Airbnb verification process though. It's really not very robust and I wouldn't rely on it.
Also, while Airbnb have sometimes caught on to these scammers, there have been guests I have reported for having fake profiles etc. and they remain on the site, able to book with other hosts, and showing 'verified ID' on their profiles, which Airbnb themselves told me to block and report.
