There's a lot of variety in the residential proxy market. Some are sourced from bandwidth sharing SDKs for games with user consent, some are "mislabeled" IPs from ISPs that offer that as a product and then there's a long tail of "hacked" devices. Labeling them generally as sketchy seems wrong.

This is a good callout - I’ve tried my best thus far to limit the use of proxies unless absolutely necessary and then focus on reputable providers (even though these are a bit more pricey).

Definitely going to give this more thought though, thank you for the comment
