First of all, .co.cc isn't a TLD. .cc is the TLD. .co.cc was a single website that was selling subdomains and not bothering to check whether malware and other nasties were being hosted on their servers. Despite several warnings from G.
This isn't about having spammy content or junk located on their site, but Malware.
Facebook banned posting .co.cc links several months back for that reason.
I saw one report that said that the .co.cc had about 50,000 malware sub-domains, which is astonishing. Most providers of free sub-domains don't have a fraction of that, because they take down sites immediately.
I really doubt that the FTC will rap G for taking down ONE domain that was encouraging malware suppliers.
G has actually been really considerate to them, giving them warnings in advance and advising individual webmasters that if their felt their particular sub-domain was legit they should submit it for reconsideration. That's more consideration than Facebook offered.
I know you hate G, but knee-jerk support for anyone opposed to them just puts you on the side of real criminals in this case.
