Why is my IP determined?

Question

Computer networks

I perform tasks on the service using imacros and firefox. I have many accounts and they block me)
VPNs of other countries are already quickly determined, I think to make Russian.
The main ip was calculated and now this stupid cloudflare appears:

At the moment I already use whoer.net for verification and configured firefox as it should, even changing the useragent + hola browser extension. I turned on hola for the service and for the social network site, but when switching to 90% of cases, a captcha begins to appear that on the screen and below is my real IP. I think hola does not have time to change it when clicking on the link. I installed an additional hotspot shield and chose Russia. It works, but after a few hours it says that the limit has been exceeded, since the program is crooked)
What are the free solutions? It takes 12 hours during the day to load sites and the speed was normal I
thought to buy a proxy for 100 rubles a month for each account one at a time, but first you need something free
