Cloudflare giving too much info to website thief

There is someone who is scraping my site and presenting the info as if it’s theirs. I have managed to obtain his server ip and blacklisted it but he just started using another ip. I then block his host’s ASN and when he tries to scrape my site. This is the message that cloudflare sends him:

“The owner of this website ( has banned the autonomous system number (ASN) your IP address is in…”

Now the attacker just knows that he can just switch hosts and continue with his evil deeds. I think cloudflare should just show access denied page with minimal info so the attacker is left to wonder.

I welcome any suggestions that could help in thwarting this person.


Hi @davreid97,

The msg you are referring to results from an IP Access rule.

If instead of using an IP Access rule to block an ASN, you create a Firewall Rule, any bots or visitors from that ASN will see a generic error message that does not explain the action being taken (other than being a block):

Error 1020 Ray ID: 5102288f2f96d91d • 2019-09-02 20:15:52 UTC
Access denied
What happened?
This website is using a security service to protect itself from online attacks.
