Because this game glorified and romanticized the topic. It portrayed it as a good thing, a fantasy, rather than as the immoral act it is. It was made PURELY for the player's sexual gratification.
Turns out that changed at some point. Now blocking someone also prevents them from replying directly to one of your posts. (They can still post in a topic you started.) The error message is oblique, and I don't remember seeing this feature announced, so it can be confusing.
And kids being kids. Plugging your ears against arguments. I can understand blocking people for various reasons. But blocking people you are having a discussion with, that is just lame and immature.
