  • i got a lot of email traffic from these CDNs clouflare,AKAMAI,FASTLY…
    the traffic identify as "proxy/vpn" and that a bad thing for affiliate marketing

  • fck, fck, fck it does not work!!!!

  • Hey Christian!

    Great content, helped in understanding the true dynamics behind the scene. Also, would need your help with few things. Where I can write you to regarding that?

  • You should hack cloudflare to find the origin ip address 😂

  • is any paid service to get real ip behind clouflare?

  • You mentioned that you look at historical A organizations to send subpoenas to. Just out of curiosity, does Cloudflare not respond to subpoenas or something? Why not just send it to them?

  • well you could make your video at work and then do a lot of blurring to block out things in the background or find another job that does not take your time away.

  • What I do is search the domain for the MX record, and then search the MX record. 8 times of out 10 the email server is the web server and so Voilà
