Hello, this is my website and I do not know what you mean by this. If you give me technical details (like the subnet your operating out of), I can take a look at it.
My webserver is using crowdsec (https://www.crowdsec.net) to ban malicious IPs and I would guess that you are somehow unintentionally affected by this.
You can also test your IP by entering it into the crowdsec website to see if it is affected.
There you go then. Thank you for confirming my determination of IP blocking. The archive link above may work for the users you censor.
Paying $1900/month for an IP address blocklist for a website? Yikes.
