Almost all "residential" proxies are run without the knowledge of the user used as the proxy. Either it's slipped in the ToS/install of other legitimate product or straight up malware. A popular method, iirc, was bundling with free VPNs.
Last I looked into the discussion, the consensus was there was no particularly reputable residential proxy service.
Edit: I probably should explain the distinction for residential proxies. Basically, if you run a site that isn't B2B, you'll find basically no organic traffic comes from data centers/server farms. So traffic from IP blocks like owned by Microsoft (Azure), Amazon (AWS), Google (GCP), etc are all highly likely to be bot traffic and throttled or outright blocked by default. If you're running a scraper or a bot, you want to get your traffic to appear to come from residential IP blocks (owned by residential ISPs).
