Have built a custom proxy solution that we built in-house, but have reason to believe that the traffic through these proxies is being viewed as suspicious by both Google and Yelp. Is there a way to test traffic to see why it might be viewed as suspicious? Like a service or something that identifies spam traffic and rates the quality of the traffic and relates what aspects of the traffic are viewed as suspicious (like missing headers, lack of cookies...)? MORE INFO:::: The proxies that we have should be very high quality because they are: * Located in the same geographic area in which they are being used * Located on residential IP addresses (fios, comcast, cox...) instead of commercial server farms * Each time we switch proxies, we use a Chrome browser extension that clears cookies and cache automatically. The reasons I think the traffic is being viewed as suspicious: * Google almost always asks for phone number verification (this only happened rarely with our other proxies) * Yelp seems to have burned 2 of the 7 accounts that we are using with it (filtered all reviews from those accounts) I feel like the problem may be something weird like perhaps we filtered out too many headers. Any help would be appreciated, thanks so much!
