False positiv

Please remove the phishing flag, since Netcraft sent a review, it was a false positive.

The Community is unable to provide any assistance with Trust & Safety matters. You have to correspond directly with them.

Can you please tell me how to contact them?

Have you checked in the dashboard of your Cloudflare account for a related notice?

Yes it is.
And then there’s Netcraft’s decision on the false positive and the domain registrar, which is all good. They unsubscribed a few days ago that they sent an email to Cloudflare, but they have not responded to the feedback for a long time.
