Is this a scam?

I met with over 30 SEO agencies and only have had 1 tell me that their strategy is to buy 100+ backlinks with varying DA. Every other agency has told me that they would be building 5-15 backlinks so I am a bit skeptic when they told me 100+ backlinks every month and told me directly they will be buying them (most say outreach).

This is with a 2k monthly budget

What do you think?

The agency is called Funnel Boost Media. If anyone has worked with them and had a good/bad experience please comment as I do not believe all these clutch reviews.

Thank you for your time.
