Your ban system is very unprofessional. Banning dynamic IPs is a cheap banning system, now my IP has changed so I’m banned because you banned other private network at any time and now I must charge other’s consecuences.
Please improve your baning system, you sell your cdns and dns services to a lot of sites globally and this system has a lot of flaws.
At least you must implement a request form to apply for be excluded of the blacklist I am tired of filling captchas. Even blaclist mail servers has this type of forms and give you the reasons of your ban. Cloudflare instead cannot give any info of the ban.
It seems like you use other blacklist systems like this https://www.dnsbl.info/dnsbl-details.php?dnsbl=dul.dnsbl.sorbs.net where my ip is listed and you can read message like this:
If you are listed on DUHL and not running a mail server do not worry about being listed here - it is normal for users in dynamically assigned IP space.
Like I said a very unprofessional work for a top IT Company like this.
