They're not obvious from the readers point of view but I would be surprised if there aren't trends in where they come from that B&O would spot, and take measures to hinder them. e.g.
- country of origin of IP address
- domain name used for email address
- specific IP addresses
- new users who have never posted an ad before; or of course those who posted scams before!
- categories being posted in
- number of photos (to get price cheap/free)
- trends for the default options for location, fuel etc
This sort of approach is common for email (and forum) spam assessment. So each ad gets a "scam score" and then based on some threshold gets rejected/requires moderated/accepted.
I think they have a fundamental error by not asking users to register. But there isn't even any verification that the phone number provided has a valid number of digits or that the postcode exists.
they are quick enough to refuse any advert that cross refers to ebay (presumably as it might get in the way of their revenue stream from phone calls) that they should be able to stop this too.
