How are these new Instagram pages getting their Reels viral?

I came across this Instagram page. It has around 800 followers, 0 following, and 16 posts, but the Reels seem to be getting surprisingly high reach.

The page :-

The bio says:

“The Official Instagram page of The 50 Reality Show

Premieres on Feb 1st only on #JioHotstar and #colorstv”

What I’m curious about is how a new page is getting this much exposure

Is there some specific trick or strategy behind how these Reels are getting pushed so aggressively?

I’m trying to understand because I’ve noticed a lot of new pages using the exact same bio, and many of them are getting their Reels viral despite having very few followers. How are all these new pages getting such high reach? Is there some specific Instagram algorithm trick, strategy, or boost happening here?

My page is getting 100-200 views only even I make high quality trending edits or lyrcial vids
