Reddit uses https, so most of the lame Internet providers are technically unable to do anything but block the entire domain, even if they were trying to only block a single webpage on it. There have already been similar cases, check this out:

On December 2, 2014, Roscomnadzor blocked GitHub because it was hosting various copies of a suicide manual. Because GitHub uses HTTPS, which encrypts data between a user's computer and GitHub, Internet Service Providers were forced to block the whole website instead of the pages in question. Complying ISP's included: Beeline, MTS, MGTS and Megafon.

I would say it's nice to realize that most countries still don't censor the Internet no matter what, but it's sad some countries that used to be ok before start doing that...
