I am a bit confused about a domain from my competition, which started this particular website around the same time as me (that would be the beginning of 2020) and has the following metrics:

Site speed is terrible, the design is copied (not even with a twist) from the leader of the niche, sometimes blocks of text are also copied from other sites.
Website is owned by Chinese, main language is English and localized in other languages. I thought that maybe localization was the key, but over 75% of the traffic is from US and UK.
How can I find out if the site is powered by some PBNs? Ahrefs doesn't report that.
