The ones that cooperate with state-sanctioned censorship? Malaysia blocks anti-government news sites via ISP DNS entries; using a 3rd party DNS bypasses the block easily.
Accusing government officials of mismanagement or outright theft of public funds is an easy way to get your domain black holed over here. That, piracy, and porn. Though I wouldn't be surprised if the latter two were thrown in solely to make the program look more legit.

Perhaps most ridiculously, Medium.com is blocked for simply hosting an article posted by a censored website. Yes, you read that right; they banned an entire domain, the vast majority of which covers nothing even remotely related to Malaysia, over a single article.
I try to be grateful they are as inept at censorship as they are oversensitive to criticism.
