I work for IPinfo. We track close to a hundred resproxy providers. So, if OP's router is compromised, the device IPs will likely be flagged.

From what I know, whenever a router is backdoored or a resproxy SDK gains access to a device to use their bandwidth, the access to that pool of devices is often shared among multiple resproxy vendors. Many resproxy vendors do not have their own SDKs for their services.

Also, as far as I know, not many resproxy operators manage their sim farms or hardware pools. It is mostly based on compromised devices or SDK access.
