How to safely promote multiple sites in regions?

Question

Search Engine Optimization

There is one drug treatment clinic that promotes websites and collects a lot of search traffic in the regions, I want to promote my topic based on them, the essence of the question is: will there be an affiliate filter from Yandex and Google? Why didn't they get filtered?
In fact, they have the same template, just a slightly different design in colors.
The name of the clinic is the same.
The content (texts) on each site is unique, the main repeating blocks: reviews, gallery, doctors in noindex tags . Phones, addresses - unique on each site. All this is done for search promotion, and gives good cuts.
How to make the same network?
What to consider, host sites on different hosting? Is it necessary to have different phones or 8800 will do, how to be as unique as possible?
Example sites:
krasnodar-narcology.ru/lechenie-narkomanii
armavir-narcology.ru/lechenie-narkomanii
rostov-narcology.ru/lechenie-narkozavisimosti
novorossiysk-narcology.ru/lechenie-narkomanii
sochi-narcology.ru/lechenie-narkomanii
Help me understand . Ready to take a paid consultation on this issue.

Answer 1

Look for the answer on forums that specialize in search engine spam.

Answer 2

Affiliation depends on many factors. Here is their list and significance - https://studiof1.ru/blog/seo/affiliat/
In general, Yandex and Google should not have a negative attitude towards such sites, because they are in different regions. In our practice, we only changed Addresses and Toponyms + rewrote the text by 5% - everything is ok.

Answer 3

Strange logic, usually this is done on a subdomain and setting the region in the Yandex webmaster for each subdomain solves all issues with duplicating content.
krasnodar.site-narcology.ru
armavir.site-narcology.ru
etc.
