They're bringing their "block user" functionality to be in line with how blocking works on other platforms and thus what users expect out of the feature. If I blocked someone on reddit before, I would have been very surprised to find that they can still see what I post. Previous behaviour would be more akin to what on twitter/instagram/whatever is referred to as "muting." Also as Drakim said: it doesn't need to be bulletproof. It's for mitigation and adding hurdles to abusive users; escalation to reporting-to-admins still exists.
