They won't have any problem with these kind of protections. But well, sure it's working well so far. I used to work on this kind of protection for a phpBB forum I have, and well, no more spam :) We start seeing more and more JavaScript (based) crawlers.

The problem with the technique you mentioned is that it is quite easy for a spammer to create the key (server side) without having to parse Javascript. Therefore your technique relies on the spammer not knowing how you are protecting the form.

I used a MD5 JavaScript to create a hash of the users' name before submitting the form. I then created the same hash in php and compared them to each other... This reduced the spam posted using the contact form of that particular site to zero. -H- I’ve used something similar a while back.
