I believer, you are suggesting these businesses as spam as the POI displays a wide area instead of a specific point.
Incidentally, Google My Business allows doing so for the service agencies.
If your business serves customers within a specific service area, you can list your service area on your Google My Business listing. Listing your service area helps let customers know where you’ll go to visit or deliver to them.
The service area feature is designed for businesses who visit or deliver to local customers. For example, it can be used by:
A business that visits or delivers to customers, but doesn’t serve customers at its business address (e.g. a plumber or cleaning service).
A business that serves customers at its business address, but also visits or delivers to customers (e.g. a restaurant that also delivers food)."
I find all the owners have claimed the POIs, display phone numbers & and there are reviews too.
Unless you have some other proof regarding phony nature of these businesses, non-appearance of a point on Maps can’t become the reason.
Thanks for your reports again. I would like to let you know that the places you reported and were considered as incorrectly added were removed from Google Maps.
I just wanted to let you know that I’ve accepted my answer as solution in order to help other Local Guides find answers on specific questions or issues when searching on the Connect. You can take a look at: How do I mark comments as solutions.
