> Back in the days when I was actively participating in all things [pidgin](http://pidgin.im), two of the frequently requested features were the the ability to find out if the other person has received your instant message (and say, not caught by some spam filter), and the ability to find out if a person has blocked you. While that is actually possible (to some extent) in some protocols, the standard answer we always gave was: yes, she (almost always, the person who asked for this kinds of features was a guy and the other person was a female) received your message and chose not to respond, and yes, if you don't see her online, she probably blocked you.

> Of course, merely working on an instant message client did not give us special insights into relationship dynamics, and we were never really sure if the answers we gave were always the correct ones. I've just figured that people who asked those questions already knew the answers, and they just needed someone else to break it to them.

Recently I contacted an old acquaintance (over a medium which, sadly, does not support the aforementioned features) and, perhaps unsurprisingly, found myself wondering about those same questions as well. This morning, while lying in bed, I remembered the standard answer that we always gave out. So here I am, breaking it to myself, yes, the message probably was not caught by a spam filter, and yes, it probably went through.
