The idea behind my cloaking technique is to allow every IP to only get once redirected from the safe to the money site and will then be blacklisted in forever. I do block on GEO IP level. However, still smart people hereby referring mainly to my niche competitors, they may try to reverse engineer what I am doing, i.e. they could use a fresh permitted IP to see the redirection. By chance I hit a website while I had my HMA (hide my ass) VPN client still on and I got following message: "Due to abuse from trolls, only regular posting members can use anonymous proxy services." Now I am wondering, how they could identify me using a foreign proxy and how to categorically block visit attempts from users who are trying to access my site?
