I disagree. Normally you can reach out to request delisting, and it's free.
As I explained, Orange's security filter seems to automatically block requests at the DNS level if your website's domain resolves to an IP listed on UCEPROTECT Level 3. In this case, that appears to be the entire DigitalOcean ASN.
You probably have standing to sue Orange for damages if they're blocking your customers from you based on bullshit criteria.
I am not a lawyer, so consult one.
