Yes but how they detected antidetect browser. On addspower there is no webrtc leak and other parameters of proxy are ok
There are many many things that can be misconfigured.
1. They can detect proxies even if WebRTC is not leaking
2. Canvas
3. AudioContext hash
4. WebGL
5. Misconfigured AD in general
Just because you use some Antidetect then it doesn't mean it will work, especially if you deal with placing reviews because most of these AD providers haven't built the software for getting through the security of such sites.
You need a lot of trial and error to find what works and what doesn't because companies are paying thousands of dollars for people to take care of their ORM needs (buying reviews) and most people who know will not help you further with this either.
The same goes for AD providers - They overpromise what their software is capable of and lately, there has been a boom of new providers but they all lack similar things so I assume (as I have also read elsewhere) that many of these programs are just reskinned but the same AD.
Also, once you mess a profile up they will flag it internally and they likely monitor all new reviews that are coming in.
Trustpilot for example, can even remove legit reviews once a profile has been flagged. Simply because they can't distinguish real reviews from fake ones if there are no cookies and history they take off everything so even if you think you have done everything right then there is always something that you will miss.
My recommendation is to first figure out how to place the reviews on your own profiles that you don't use (buy a domain or two) and only then start placing them where needed.
Hope that helps.
