Blog Rejection after purchase

Hi, 

I bought the blog simplyum.com 3 months ago. It was already monetized via Journey. Since taking over, I’ve improved posts with more and better images, doubled the number of articles while keeping the same high quality, and my Pinterest traffic is steadily growing. 

Despite this, my reapplication was rejected, and the rejection only links to a vague generic page, so I don’t know the exact issues.

Could anyone who’s familiar with Journey share insights on what specific factors might cause a site like mine to be rejected, or how I could identify and fix them before reapplying? 

Any guidance would be really appreciated!

Thanks!
