NewPipe has it's own library NewPipeExtractor and does the work on your device, so IP bans aren't really a problem compared to a hosted instances where multiple clients access youtube through the IP of the instance.

Piped is an alternative to Invidious which uses the NewPipeExtractor library: https://github.com/TeamPiped/Piped
But instances with high traffic or 'suspicious IP Adresses' can still be banned very quickly.
