May I add a comment to help with people who use proxy server to run their "shadow operations". Hmm... I understand that rotating residential proxy costs a bit more than static IP or data centre IP or shared residential IP plan. But you need a proper proxy server with rotating IP NOT shared private meter rotating residential IP to go CTR manipulation. And you do need to spend money to make money. I don't know if I am allowed to name names here for the company I use for proxy server service. It's a bit pricey around $60 usd a month may be for a 5 port private meter residential proxy, rotating every 5 mins, and I can geo-tag the region / city, hold the IP for a longer period so it doesn't release and rotate every 5 mins, recall IP so I can use it for warming up google accounts for google map manipulations / google review manipulations.
I suppose you want something as big as CTR, it will easily be over 500 GB or 1 TB a monthly basis, so shared residential plan with a limit of bandwidth probably won't work for something as big as CTR for google map / web SER ranking. Well if you are running a site that have pictures / videos and stuff, and you send 5000+ "visitors" there every day, you do the math, so even if 500 MB bandwidth 1 visitor, one day is already 2500GB
