Product Hunt was a complete waste of time for us

We launched on Product Hunt expecting exposure to potential customers.

What we got instead:

Tons of spam emails from agencies and companies trying to sell us marketing, SEO, backlinks and growth services
Zero actual customers from the launch

The signal-to-noise ratio was terrible, it felt like our email address was simply harvested by people trying to sell us something.

For us PH generated more spam than users.

Has anyone else had the same experience recently?
