How do they get those Backlinks from Google?

How these guys got those links from Google Maps?

I know if I change the URL to mine I'll get the link from Google but as you can see, at SEMRush report, they are into categories, for example: Internet & Telecom > Web Services > Search Engine Optimization & Marketing

Please, anyone can give me some light on this?

Thank you very much.

Don't waste your time with that. These links don't help you ranking.

Ok thank you very much, a client just asked me about those links.
God bless you.

here's a list with those links:

Just replace the website (pornhub.com) in this list with your website and you'll get the same links as in your image. But like @chewba said, these links will not help you rank
