I have a hypothesis of the new SEO being "clean slate brands"
Code:
barry@paragon-DS-7:~$ whois -h whois.afilias-srs.net indiansex.porn
NOT FOUND

Sometimes it is easier and cheaper to start all over with a new plan.
You can keep what you have and milk it out.
This is just an example of TLD branding.
