As someone wrote above, you need several things to farm the accounts successfully.
Here are my top favorites for Google Ads account creation.
- Anti-detect browsers. I am using Dolphin anti-detect browser: https://anty.dolphin.ru.com/en/. They have actual fingerprints, management for browser profiles, and teamwork options. They have a BHW sales thread https://www.blackhatworld.com/seo/dolphin-anty-a-modern-antidetect-browser-10-free-profiles-for-everyone.1350973/ too.
- SMS numbers for verification/activation. I am using https://mobilesms.io/. Clear dashboard, several payment options. They have options for long-term renting numbers.
- Debit/credit cards - I use Stripe, Mercury, and other fintech banks for cards. For me, this is the hardest part of the whole process.
- Good proxies. I am using proxies from https://proxyempire.io/. They have a large pool of mobile/ residential proxies from 165 countries.
Some mistakes that I found via trial and error.
- Fake names, and addresses, from sites with fake name generators.
- Too quick and mechanical actions after profile creation. For example, copy-paste information from your text file to the dashboard.
- No activity on the Google profile. Reading news, watching some YouTube videos, browsing like a normal person.
- Black hat/grey hat campaigns from the first day.
Sorry for the long answer. TL;DR of your question is https://proxyempire.io/
