Kind of crazy to me that anyone would block an entire TLD. This timeline is bizarre. How often and with what services do you find zip blocked? Genuinely curious
My employer blocks it on our work computers. Looking around it seems like this is commonly done because one of the main uses of the .zip tld is to spread malware by faking links to zip files using "/" look alike characters and other URLs that look like download links to zip files.
I had little opinion on .zip but this convinced me to go figure out how to block .zip tld. Why would someone risk all those attack vectors when there is so much available on the many other tlds. I could see myself getting caught by many of them.
