As "an experienced web developer", you think that might have helped?
I'm sure Apple wants URLs to be available for sharing, so I'm curious what sort of URL filtering you have in mind? They've got a few traditional options, such as requiring a degree of participation, but that's easy to circumvent. Or they can disable URL sharing for replies, but that's the nuclear option. It isn't as trivial a decision as people make it out to be.
Spam filtering? This is even more the case. Developing efficient spam filtering, aside from being a bandaid on a gaping wound rather than a cure, is even more difficult to implement. If Apple does take that avenue it is a solution they will have to develop through a game of studying a cat-and-mouse exchange. Ideally they'll aim for a solution which attacks the problem at an earlier stage.
The sarcasm is fine given I was sarcastic initially, but the point I want to stress is that it is extremely hard to appreciate the complexity of what this problem can become without an understanding of how extensive this spammer vs. exchange medium is on big platforms, be it a social network, forum, or even email.
So really, buzz words (like 'spam filtering' and 'URL filtering') don't mean much without the technical backing.
