Only relevant to large sites. Like WAHa said, it raises the bar.

Besides, there are ways to prevent that too. Ensure that the referrer is always your site, and prevent any IP or block of IPs from requesting too many captchas, and their job becomes a lot harder.

If you make it hard enough, hopefully the undesirables will move on.

Depends for what. You normally only see it once when signing up for an account somewhere. It's a tiny investment for a large collective return (which is steadily diminishing).
