Generally not really. Residential proxies are services that can provide customers with the ability to send and receive traffic from a wide range of apparently legitimate networks (i.e. people's home internet connections). Almost always this is done without the informed consent of the person who owns the device that is used as a proxy, whether it be buried in some agreement somewhere or just outright malware.

The biggest danger is that said proxies can also allow access to internal networks, and as you might guess from how they are installed, are not usually operated by the most scrupulous of organizations.
