Best options are either a personal VPN service with a VPS provider. It won't look residential but it won't be flagged as a VPN.
For truly resential you have only two options.
- the easy option is to ask a friend to setup tailscale on a computer at home and have it be your exit node
- the other option is to look for a small and local VPS provider, while they don't look 100% residential, some of them do look residential enough that outside of manual inspections they look residential.
