How do they Boost DR like this?

Hello guys!
Im trying to figure out what kind of sorcery is this.

Look at this regular dummy blog:
http :// miwulazi dot eklablog dot com

The ahrefs shows DR is 82 and it have 15K ref domains. The most of them are redirects I asume.
Miwulazi blog has up to 60k hidden link redirects on its html code page.

I tried to achive the same DR with my test blog:
https :// simioniii dot blogspot dot com - and result is nothing.
Ahref doesnt crawl those hidden links in code. I tried GSA and comments links (1 day after posting) and no result yet.

Please, help me to understand how to force ahref to crawle my redirects on Simioniii blog.

Redirects crawling is an another thing mate , use good redirects to push DR .

There are almost 60k redirects. I checked manually and some of them really good.
But I don't understand your answer. Are you meaning only good redirect will appear on ahrefs?

I notice there are sites in the list which totally returning initial site and its creates loop. The main point that I copied all from
http :// miwulazi dot eklablog dot com
to my blog
https :// simioniii dot blogspot dot com

just changed the backlink to my blog. It have to work as i didn't change anything else but it do not. Why redirect works for Miwulazi and do not for Simioniii? That is the strange thing.
