Hello, I am new to the Apify. I am trying to integrate influencer scraper to N8N. Even, I change the keywords, search result is same. I am not sure what the reason is...

This all depends on the specific actor you're talking about. You should try to contact the actor developer.

How can I contact with actor developer?

On the actor page in the console there is an Issues tab where you can report this to the developer.
