I wanted to give a heads up about private proxies. Normally I would check the proxies either by using the checker in GSA SER or /and Scrapebox or websites like ipchicken. And a few months ago I bought into the private proxy service that was being promoted (before) was only 39$ discounted for thousands of IPs rotated ...... All was good, the service was up and down, but all seemed well. But I checked the IP that were to hide my vps ip and i was SHOCKED to see that my real ip was being shown too.
You can see yourself - check your Proxies to be sure your really not being logged with your working vps ip. This could be how some are getting emails from their host vps services?http://www.proxyblind.org/anonymous-proxy-server.shtmlhttp://yourrealip.com/my-ip-address-html/
I have a picture of the one. I marked out my local ip - but you see that it was there at the bottom part and it should NOT be showing.
