Organization Filters - Top-level Domain
Currently, we have implemented spam, block, and allow lists to filter registered domains. However, we are unable to add top-level domains to these lists. As a cybersecurity professional, I am fully aware of the importance of preventing phishing attacks and recognize that numerous top-level domains are commonly exploited for malicious purposes.
Cloudflare published a comprehensive article on this topic earlier this year.

My proposal suggests that we also permit only the top-level domain (TLD) to be added to spam, block, and allow lists.

Pretty sure this can already be done via custom filters, ends with. Something like "ends with .tld" should already do this.

I would like to be able to do this as a personal user as well. I receive a large amount of spam, and exclusively spam, from a TLD that I'd like to block wholesale.
