About filters

Recently, re-reading the logs of the anti-spam bot, I came across a message from some girl:

  Do you know Russian? 

(spelling and punctuation preserved)
Of course, I know Russian better than this girl. But the fact is that the text in my anti-spam control is written in English. The question is simple, but it turns out that the anti-spam bot is a kind of filter that almost unmistakably brushes aside determines those people with whom I, most likely, will be uninteresting to communicate. From time to time I read these logs, sometimes it is funnier than jokes on bash. And, having read something interesting, I look in the profile, and then add a person to the contact list.

What I am leading to ... There are habrechelovekie who read only what zahabreno, because they believe that if the post is mined, then you should not waste time. Or maybe it's worth reading? After all, comments are often more interesting, and if the post is actively minus, it means he did not leave people indifferent.
