Not really, .ml stands for Mali domain. And just because someone believes in Marxist principle or communism isn’t a issue. Personally for me why I am wary of .ml domain is because often I do see people posting obvious Chinese and North Korean propoganda with shady source and wild claims and their refusal to accept criticism of China or other communist past and present regimes. Also they get really defensive and assume you are pro west or pro imperialism when you happen to criticize china for something and then their whole argument would be bashing the west when both are to fault.
