Name servers of multiple domains changed by a hacker

The name servers of multiple domains with a particular registrar have been changed repeatedly by unidentified hackers to cause losses. For example a domain which had content related to torture, pain, human rights abuses has been changed to a parking page, reducing the number of page views, advertising revenues.
It appears that some registrars are not secure and it is advisable to transfer the domain names at the earliest to the secure registrars. It is easy for the shameless lazy greedy pampered fraud cbi/r&AW employees goan gsb frauds riddhi siddhi mandrekar, asmita patel, nayanshree and their fraud associates to shamelessly and falsely claim that they own the domain names, as they do not spend any money at all on the expenses or do any work at all. The real domain investor has to be careful to ensure that the domain names make enough money to cover all the expenses.
