When I was in high school, I worked for the IT department, and I can completely see why a Christian site would be blocked but not a Muslim one.
We had 'block lists' for vendors that were updated to keep the main stuff 'blocked'... but a lot of blocks were requested. For example, teachers were wasting time on stock market websites, so the principals office called us to block those, etc. We were just IT, not 'the keepers for freedom' - plus our accounts were unfiltered lol so we didn't care.
As soon as they realized how fast and easy we could block stuff, it became a regular thing.. and, there were all kinds of situations where we pondered "Why block this, but leave this open?" .. but, in the same way China censors the main internet, but, darknets are left mainly untouched.. people censor what they know exists, and just as powerfully, what is in their interest to block.
Hypothetically, maybe people were wasting lots of time on the Christian site, it raised a red flag, and someone got told to block it. But, people weren't wasting time on the Muslim site (Because, they're not muslim hehe)... so it didn't get blocked. It wasn't visible, it wasn't a perceived problem.
What I don't understand is why that kid spent any time on that computer system after he discovered that they had blocked porn.
Alex,
It comforts me that I wasn't the only one thinking that.
