How to flag mass post approval in Staging Ground

I was looking at the review history of Staging Ground and found someone who approved about 50 posts within minutes.

Here is some of the approved questions:

• Tabulator with multiple tables in a single page is sharing column calculations from one table to all tables, and more

• React Native: How do I render a component on my previous page when I pressed on my button in the next page?

• SoftProdigy System Solutions

The first one lacks proper formatting, the second lacks relevant information and the last one is literally ads.

What can I do to report this behavior?
