Two important points to be noted:
1. The troll claims to not be able to understand Bahasa Melayu, and yet he (or she) subsequently replied to my provocation in the language.
2. The troll claims to be a “Muslim” and yet clearly uttered invectives which proves this to be false.
Conclusion: The troll is a habitual liar. And I think I have a good idea who this person is.
