Almost two years ago I wrote a post about Twitter’s decidedly useless block functionality, that stated the reasons why this ‘block’ isn’t actually a block at all. Why? Because it doesn’t actually block anything.
Block somebody on Twitter and they can still read your timeline, send you replies and retweet your messages, giving the impression to others that you are still friends. So unless you take the rather drastic step of making your timeline completely private, which is overkill and a bad idea for most users, certainly if they want to use Twitter for business, a block is almost a complete waste of time.
And there’s a really simple way they could do it. In fact, all it needs is one extra checkbox in your settings.
