residential proxy
A request relayed through a consumer ISP address so that it is indistinguishable, at the network layer, from a person at home. It defeats ASN blocking and it defeats feed verification, because the address is in nobody's operator feed and belongs to nobody's data centre. Any forged-crawler rate computed against operator feeds is therefore a floor: the forgeries that used residential addresses were never counted, and no server-side method can count them.
