We recommend the entire package listed, the more bullets in the gun the better. There's not any one magic bullet.

Sent you a PM at Ozz's place.

I don't see anything added to 3.x
Maybe 4.x but I really doubt it too..

It may be added to 5.x but no one uses that pile of junk ;)

Lol, maybe something a lot down the line, we hope.

Why would someone add something that is defeated?

There's no way to defeat real human though.

For a very long time I haven't faced such things called robots, all of them are human. They might be paid to do this, and we can never stop them completely.

As the new technology of google is preventing robots to spam, nothing new.

Sure there is. It's been done and it's done every day.

Also it is just plain annoying. Why rely on something that can and will be defeated, if it is not already. :)

That is true, yes. I wouldn't rely on this, but I would like to see one do a mod for it or something. Just to see how it turns out and whatnot.

But, why?

1) It is annoying
2) It is useless as programs like XRumer probably have it defeated.
3) There are other un-annoying, un-defeated ways to stop spammers.

Okay, you have a point there. I'll leave it at that. :P
