With many of these big anti-bot services like Google ReCaptcha, it's not even specialized anonymity tools that can cause shadow banning, just unusual user-agents.
All of these have independently caused me to get into endless ReCaptcha loops: firefox on android, smartphone with unusual screen resolution, clean browser profile with VPN.
It's so common that I now default to using duckduckgo, which never blocks me. I doubt DDG has a lower DDoS/Resources ratio than Google. Some companies are just lazier and less principled than others.
