As a domain owner you have enough to deal with from ICANN moves to price increases.
You never ever develop anything of importance to you on someone else’s property. Use social media and other apps to feed your website, but the CentralNic retirement of several LL.com domains illustrates why you never trust anyone else with your business. From links to SEO, social mentions etc… A sub-domain is never worth the risk in my opinion.
The owner of Hotel.Kr.com posted this on Namepros:
This is how they respond following deletion of www.hotel.kr.com with offer of new domain such as hotelkr.xyz
We respect that you are not happy with the services that are being discontinued. We have continually advised that alternative substituted services have been offered to you. You have continued to reject the offers to provide continuity of services. You must accept the consequences if you refuse to take up the new domains and that you may face consequences of your decisions.
We reserve our rights whatsoever nature.
