I'm interested in looking at newly registered domains for bad actors.

There are services out there that offer zone files for 'all' TLDs but are too expensive for individuals not backed by a company to pick up the bill. I've also found some free lists but they appear to be incomplete.

So I've gone down the route of attempting to obtain zone files or at least newly registered domain lists from TLDs themselves. Obtaining zone files for gTLDs is straight forward with ICANN's CZDS service. But obtaining zone files for ccTLDs appears to be quite interesting. I attempted to Google but couldn't find anything so I've started to email ccTLDs; it already feels like I'm spamming since I'm sending the same email - I've only sent it to 10 TLDs so far. It looks like there are a few hundred ccTLDs.

Is there a better method than emailing each ccTLD and hoping for the best?
